Reland #19396 with a fix for improper scale that was affecting internal tests
Tested: Ran all unittests, ran internal tests, and ran workstation on Fuchsia

This improves raster cache control from apps and enables
GPU acceleration for some offscreen workloads that would
fallback to software.
Test: PlatformViewTests.GetGrContextTest

This change creates the scenic session with request to Focuser. The
focuser is used to request focus to a view, given it's ViewRef. The call to
requestFocus is made from PlatformView messages channel, which will
be used from Flutter side by ChildView.
Adds a PlatformView unittest for the requestFocus method.

The fuchsia code around metrics and sizing was just sending this
information through a side-channel, when the engine already had the
information available. So, delete all of it to make future CLs simpler.
Additionally, the SceneUpdateContext has many unneccesary dependencies
re: metrics and PaintTasks. Break those to make future CLs simpler.

* Add PlatformView support for Fuchsia
This change allows embedding views provided by fuchsia components into
a flutter app running on Fuchsia. This conforms to Flutters idiomatic
approach to composite PlatformView alongside other rendered layers.
This uses the `view embedder` infrastructure to allow
`PlatformViewLayer`
to hold fuchsia views. This is meant to eventually supplant the legacy
`SceneHost` and `ChildViewLayer` mechanism to embed fuchsia `ChildView`.
To see how this will get used check out:
https://fuchsia-review.googlesource.com/c/experiences/+/398536/6/examples/hello_experiences/lib/fuchsia_view.dart
Includes unittests for platform_view.cc.
Note: This change has no impact on the legacy code to embed fuchsia
views.
* Rename OnCreateViewMethodCall to OnCreateView
Same for OnDestroyViewMethodCall to OnDestroyView

In order to better support different products on Fuchsia, we should
change performance-sensitive attributes based on config files passed in.
This change does so for `vsync_offset`.
Expose scenic's ability to toggle wireframe debug
rendering of view bounds in flutter_runner. This is done
by registering a new function on the platform_views channel
with the PlatformView.
Note: Unittests have not been enabled, will enable once we
have sufficient infra.
