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.

Since Flutter tracing is wired up to Fuchsia system level tracing (and
that includes Skia tracing within Flutter), it makes more sense to
enable Skia tracing by default on Fuchsia, and to control Flutter Skia
tracing, rely on whether Fuchsia system tracing is enabled, in progress,
and contains the "skia" category.
