cc: VideoLayerImpl VideoFrame::TEXTURE_YUV_420 support.

VideoFrame can carry YUV native textures.
After crrev.com/1127423006 VideoResoucesUpdater will create the
appropriate VideoFrameExternalResources.
This change makes VideoLayerImpl deal with a VideoFrame with a
NATIVE_TEXTURE format and a TEXTURE_YUV_420 texture format.
