* 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 Co-authored-by: Sanjay Chouksey <sanjayc@google.com>
