v4l2_codec2: Remove media::ColorPlaneFormat and media::VideoFrameLayout

This CL removes all uses of the media::ColorPlaneFormat and
media::VideoFrameLayout types that were copied from Chrome. All uses
of ColorPlaneFormat are changed to the VideoFramePlane type in
Common.h. To replace the Chrome VideoFrameLayout a much simpler type
was introduced in Common.h.
