Previously, the base class PlanarYuvBuffer was used directly. Having
separate base classes will allow us to improve type safety in some
places.

VideoFrameBuffer is currently hard coded to be either I420 or Native.
This CL makes VideoFrameBuffer more generic by moving the I420 specific
functions into their own class, and adds an enum tag that represents the
format and storage type of the buffer. Each buffer type is then
represented as a subclass. See webrtc/api/video/video_frame_buffer.h for
more info.
This CL also adds support for representing I444 in VideoFrameBuffer
using the new interface. Possible future buffer type candidates are
RGB and NV12.

Moves webrtc/common_video/rotation.h and parts of
webrtc/common_video/include/video_frame_buffer.h and
webrtc/video_frame.h, and adds to a new GN target api:video_frame_api.
