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. SCN-1351 #done Change-Id: Id4c8ef65cc39a967087d7fa6c9f595da8cfe5f01
