  RenderViewTransitionCapture should be able to use its ImageBuffer directly as 
layer contents.

Reviewed by Kimmo Kinnunen.

The existing setContentsToImage path is disabled for UI-side compositing, due to
lack of support for a remote NativeImage.  Adds a new option that is supported
with UI-side compositing, setContentsToImageBuffer.

Change RenderLayerBacking to detect RenderViewTransitionCapture as a suitable
image source, and pass the ImageBuffer through to the GraphicsLayer.
