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.

This makes it so that the platform views can be passed
an arbitraty CreateVsyncWaiter callback that lets us inject
a vsync waiter other than just the simulated monotonic vsync waiter
that currently exists.
The converters are still in a separate target that must be included manually. This allows targets that depend on FML but not Dart runtime not have to depend on the runtime.
Adds a test that includes this target and tests image decompression from assets. There is also a test for the standalone DartConvertor in shell_unittests but not in fml_unittests be cause FML uni-tests cannot yet launch a VM. I will work on adding fixtures for those.
This ensures we rasterize into the canvas passed in as subclasses may reimplement AcquireFrame in different ways that don't utilize the canvas object passed in (such as Fuchsia's flutter_runner::CompositorContext).
This re-enables thread safety checks for WeakPtr. WeakPtrs can't be used on a thread other than the one the WeakPtrFactory was created on.
This fixes the unit tests and adds a getUnsafe() method to WeakPtr to work around the remaining unresolved locations where we are using WeakPtr unsafely.
Since this is currently only meant to be used by the embedding internally, the setter in Objective-C is only exposed via the FlutterDartProject private class extension. Unit tests have been added to the shell_unittests harness.

Texture unregistration is finished on the GPU thread. The FlutterTexture implementation might not know when it is finished which leads to a race condition. Adding this callback so the FlutterTexture is aware of end of the unregistration process.
The rasterizer may only be accessed safely on the GPU task runner. The test was accessing the same on a non-engine known task runner instead (i.e the tests main task runner).
Crashes previously reproducible on all platforms with the following filters: `--gtest_filter="*ShellTest.SetResourceCacheSize*" --gtest_repeat=-1 --gtest_shuffle --gtest_random_seed=1988` at run ~400.
