Embedders can now notify shell during startup about the various displays and their corresponding settings. Adds a notion of Display update type which can later include chages to displays during runtime such as addition / removal / reconfiguration of displays. We also remove the responsibility of providing the refresh rate from `vsync_waiter` to `DisplayManager`. Rewires existing platform implementations of the said API to use `Shell::OnDisplayUpdate` to notify the display manager of the startup configuration. DisplayManager is also thread-safe to account for rasterizer and UI thread accesses.

Added a new `FlutterEngineAOTData` argument to `FlutterProjectArgs`. Embedders can instantiate and destroy this object via the new `FlutterEngineCreateAOTData` and `FlutterEngineCollectAOTData` methods provided. If an embedder provides more than one source of AOT data to `FlutterEngineInitialize` or `FlutterEngineRun` (e.g. snapshots as well as `FlutterEngineAOTData`), the engine will error out. Resolves: https://github.com/flutter/flutter/issues/50778

`FlutterEnginePostCallbackOnAllNativeThreads` schedule a callback to be run on all engine managed threads. The engine will attempt to service this callback the next time the message loops for each managed thread is idle. Since the engine manages the entire lifecycle of multiple threads, there is no opportunity for the embedders to finely tune the priorities of threads directly, or, perform other thread specific configuration (for example, setting thread names for tracing). This callback gives embedders a chance to affect such tuning. Fixes flutter/flutter#49551 Fixes b/143774406 Fixes b/148278215 Fixes b/148278931

This is a non-breaking addition to the stable Flutter Embedder API and exposes a subset of the functionality provided by Dart_PostCObject API in a stable and tested manner to custom embedder implementations. Send port acquisition can currently be done as described in the unit-test but there may be opportunities to extend this API in the future to access ports more easily or create ports from the native side. The following capabilities of the the Dart_PostCObject API are explicitly NOT exposed: * Object arrays: This allows callers to create complex object graphs but only using the primitives specified in the native API. I could find no current use case for this and would have made the implementation a lot more complex. This is something we can add in the future if necessary however. * Capabilities and ports: Again no use cases and I honestly I didn’t understand how to use capabilities. If needed, these can be added at a later point by appending to the union. Fixes https://github.com/flutter/flutter/issues/46624 Fixes b/145982720

This exposes platform_view_id on the embedder API's FlutterSemanticNode. In bd0f9085 (#8055), platformViewId was added to SemanticsNode. This field is non-zero when the SemanticsNode represents a platform view and is typically used by embedders as a means of identifying locations where a platform view's 'native' accessibility tree should be injected into the platform-specific accessibility tree constructed by the embedder. Due to the intended use of this field, the Flutter framework is meant to enforce that this node has a child count of zero.

For embedder code that is configured for both AOT and JIT mode Dart execution based on the Flutter engine being linked to, this runtime check may be used to appropriately configure the `FlutterProjectArgs`. In JIT mode execution, the kernel snapshots must be present in the Flutter assets directory specified in the `FlutterProjectArgs`. For AOT execution, the fields `vm_snapshot_data`, `vm_snapshot_instructions`, `isolate_snapshot_data` and `isolate_snapshot_instructions` (along with their size fields) must be specified in `FlutterProjectArgs`.

Embedders may use this to specify a thread whose event loop is managed by them instead of the engine. In addition, specifying the same task runner for both the platform and render task runners allows embedders to effectively perform GPU rendering operations on the platform thread. To affect this change, the following non breaking changes to the API have been made: * The `FlutterCustomTaskRunners` struct now has a new field `render_task_runner` for the specification of a custom render task runner. * The `FlutterTaskRunnerDescription` has a new field `identifier`. Embedders must supply a unique identifier for each task runner they specify. In addition, when describing multiple task runners that run their tasks on the same thread, their identifiers must match. * The embedder may need to process tasks during `FlutterEngineRun` and `FlutterEngineShutdown`. However, the embedder doesn't have the Flutter engine handle before `FlutterEngineRun` and is supposed to relinquish handle right before `FlutterEngineShutdown`. Since the embedder needs the Flutter engine handle to service tasks on other threads while these calls are underway, there exist opportunities for deadlock. To work around this scenario, three new calls have been added that allow more deliberate management of the Flutter engine instance. * `FlutterEngineRun` can be replaced with `FlutterEngineInitialize` and `FlutterEngineRunInitialized`. The embedder can obtain a handle to the engine after the first call but the engine will not post any tasks to custom task runners specified by the embedder till the `FlutterEngineRunInitialized` call. Embedders can guard the Flutter engine handle behind a mutex for safe task runner interop. * `FlutterEngineShutdown` can be preceded by the `FlutterEngineDeinitialize` call. After this call the Flutter engine will no longer post tasks onto embedder managed task runners. It is still embedder responsibility to collect the Flutter engine handle via `FlutterEngineShutdown`. * To maintain backwards compatibility with the old APIs, `FlutterEngineRun` is now just a convenience for `FlutterEngineInitialize` and `FlutterEngineRunInitilaized`. `FlutterEngineShutdown` now implicitly calls `FlutterEngineDeinitialize` as well. This allows existing users who don't care are custom task runner interop to keep using the old APIs. * Adds complete test coverage for both old and new paths.

Account for root surface transformation on the surfaces managed by the external view embedder. (#11384) The earlier design speculated that embedders could affect the same transformations on the layers post engine compositor presentation but before final composition. However, the linked issue points out that this design is not suitable for use with hardware overlay planes. When rendering to the same, to affect the transformation before composition, embedders would have to render to an off-screen render target and then apply the transformation before presentation. This patch negates the need for that off-screen render pass. To be clear, the previous architecture is still fully viable. Embedders still have full control over layer transformations before composition. This is an optimization for the hardware overlay planes use-case. Fixes b/139758641

This patch allows embedders to split the Flutter layer tree into multiple chunks. These chunks are meant to be composed one on top of another. This gives embedders a chance to interleave their own contents between these chunks. The Flutter embedder API already provides hooks for the specification of textures for the Flutter engine to compose within its own hierarchy (for camera feeds, video, etc..). However, not all embedders can render the contents of such sources into textures the Flutter engine can accept. Moreover, this composition model may have overheads that are non-trivial for certain use cases. In such cases, the embedder may choose to specify multiple render target for Flutter to render into instead of just one. The use of this API allows embedders to perform composition very similar to the iOS embedder. This composition model is used on that platform for the embedding of UIKit view such and web view and map views within the Flutter hierarchy. However, do note that iOS also has threading configurations that are currently not available to custom embedders. The embedder API updates in this patch are ABI stable and existing embedders will continue to work are normal. For embedders that want to enable this composition mode, the API is designed to make it easy to opt into the same in an incremental manner. Rendering of contents into the “root” rendering surface remains unchanged. However, now the application can push “platform views” via a scene builder. These platform views need to handled by a FlutterCompositor specified in a new field at the end of the FlutterProjectArgs struct. When a new platform view in introduced within the layer tree, the compositor will ask the embedder to create a new render target for that platform view. Render targets can currently be OpenGL framebuffers, OpenGL textures or software buffers. The type of the render target returned by the embedder must be compatible with the root render surface. That is, if the root render surface is an OpenGL framebuffer, the render target for each platform view must either be a texture or a framebuffer in the same OpenGL context. New render target types as well as root renderers for newer APIs like Metal & Vulkan can and will be added in the future. The addition of these APIs will be done in an ABI & API stable manner. As Flutter renders frames, it gives the embedder a callback with information about the position of the various platform views in the effective hierarchy. The embedder is then meant to put the contents of the render targets that it setup and had previously given to the engine onto the screen (of course interleaving the contents of the platform views). Unit-tests have been added that test not only the structure and properties of layer hierarchy given to the compositor, but also the contents of the texels rendered by a test compositor using both the OpenGL and software rendering backends. Fixes b/132812775 Fixes flutter/flutter#35410

This exposes the `Settings::leak_vm` flag to custom embedders. All embedder unit-tests now shut down the VM on the shutdown of the last engine in the process. The mechanics of VM shutdown are already tested in the Shell unit-tests harness in the DartLifecycleUnittests set of of assertions. This just exposes that functionality to custom embedders. Since it is part of the public stable API, I also switched the name of the field to be something less snarky than the field in private shell settings.

embedder.h is a C API, so has no namespace, and only uses 'Flutter' as a prefix for most symbol names. This creates potential collisions with other code; for instance, FlutterEngine is the name of a type in embedder.h, but also an ObjC class in the iOS Flutter API. This adds a macro that can be set to prefix symbol names, allowing clients (notably, the macOS embedding) to adjust the names used by the embedding API internally without breaking ABI or API compatibility for the standard engine build. Currently the macro is only applied to FlutterEngine, since that's the symbol that is currently at issue, but it can be expanded to other symbols in the future.

Messages sent to the embedder host may be one-way messages with no response handler. If the host calls FlutterEngineSendPlatformMessageResponse on a one-way message, then just delete the message response handle. Also update the documentation to indicate that FlutterEngineSendPlatformMessageResponse must be called for all messages. Previously the docs implied that some FlutterPlatformMessage objects may have a null response_handle. The embedder will now set a response_handle for every message (even if the sender does not expect a response).

Rather than hard-coding the type of incoming events to mouse, and synthesizing a primary button press for kDown/kUp, expose device kind and buttons in the API. For backwards compatibility, if the type is not set, the old behavior is used. If an embedder sets the type to mouse explicitly, however, they must also set correct button information. For the touch type, the API abstracts away the framework's internal expectation that a button is set for touch down/move for simplicity. Fixes flutter/flutter#32854
