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

* Introduce `SkiaObject` an object that's backed by Skia C++ objects that need to be explicitly deleted.
* Automatically delete `SkiaObject`s at the end of frame.
* Make `SkPaint` a `SkiaObject`.

Because `SkiaObject`s are deleted at the end of the frame, the object can be reused as many times as necessary within the frame. `SkPaint` in particular is a fairly expensive object. Reusing this object, for example, on `drawRRect` drops the canvas paint time by 30%.

Add a test to verify behavior discussed in b/143612326

If a new fallback font is discovered during paragraph layout, the fallback
font cache in txt::FontCollection will use that font in future layouts.

However, that cache is not available if the new fallback font needs to be
used for other characters within the current layout.  This PR adds a cache
to minikin::FontCollection and checks whether fonts in the cache can handle
a character before calling the fallback font provider.

See https://github.com/flutter/engine/pull/13257
