This condition may arise when the embedder passes in a path to a non-existent
dylib. Instead of crashing, the embedder will now return an error response.

This reverts commit ef3aa014. This address the use case of an internal customer. In a subsequent patch, I will add a test for this functionality. Instead of removing support for the same from tonic (along with the stuff surrounding filesystem access and package map handling), I’ll rework the same to use FML to avoid code duplication and maintainability.

The current count is determined from std::thread::hardware_concurrency which can
return zero. Even in such cases, the implementation may not return a loop with
no workers. There are numerous components that depend on having non-zero workers
in the queue.

* Revert "Web PargraphStyle TextHeightBehavior integration (#16075)"

This reverts commit 86682a2d.

* Revert "Engine/LibTxt/dart:ui impl of TextHeightBehavior (#15087)"

This reverts commit cbf4536d.

This is in the same vein as https://github.com/flutter/engine/pull/16081 but
includes holding the mutex when updating all members in the Captures struct
instead of just when tracking thread IDs.

This is only used in the command line VM. The only conceivable use of this would
be with IsolateMirror.loadURI which is not supported in Flutter or used in known
embedder API implementations (even ones that use mirrors).

This was introduced in
https://github.com/flutter/engine/commit/c5329ef5c42a4b55b03ab7b84f1cbcecf43baf7d.

The assertion was originally written to check that more than 4 threads were
managed by the engine (UI, Platform, GPU, IO + ConcurrentWQWorkers). However,
the assertion actually only checked the count of workers in the ConcurrentWQ. As
written, this assertion would fail on all hosts with a hardware concurrency of
less than 4. Remove the assertion. The engine threads count and its assertions
already check callbacks on workers. So this check was incorrect and redundant.

This is unused.

`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.

Tonic used to be used by multiple consumers outside of Flutter Engine. Due to
this, it has an unnecessary abstraction layer as well as utilities duplicated in
FML and other engine subsystems. The sole user of Tonic is now the Flutter
Engine. It is intended that the Flutter Engine team now owns this subsystem,
remove unnecessary utilities and document the headers. This is the first step in
the transition. No history is being imported as the initial history was already
lost in the transition of this component to fuchsia.googlesource. As this
component was unmaintained there, I could see no additional value in importing
the history of the patches there.

No functional change. Just moved the repo from //third_party to
//flutter/third_party and updates GN refs.

Currently we're automatically registering plugins both when the
FlutterEngine is constructed and in the `flutter create` template, when
FlutterActivity#configureFlutterEngine is called. The initial
registration is too early to contain a reference to the activity and the
second registration can cause problems in some plugins.

This alters the flow so automatic registration happens in two discrete
places, and contains the `activity` in its first and only call for most
apps.

1. We're no longer automatically registering plugins on `FlutterEngine`
in any of our activities/fragments at construction time. But since the
FlutterEngine default constructor still automatically registers plugins,
anyone constructing the engine themselves (for example, in a service) is
still going to get automatic registration at `FlutterEngine`
instantiation time.
2. We now automatically register plugins in the base `FlutterActivity`'s
`configureFlutterEngine` hook. Anyone using `FlutterActivity` (or
`FlutterFragment`) should be automatically registered once that hook is
called. Right now the `flutter create` template overrides the base class
method with a subclass that registers everything manually in the same
spot. But with this in place we can safely recommend to remove the
subclass and rely on this hook to automatically register going forward.
Registering at this time means `activity` is set correctly.
