Android: Stop using VideoRenderer class

This CL updates the WebRTC code to stop using the old VideoRenderer and
VideoRenderer.I420Frame classes and instead use the new VideoSink and
VideoFrame classes.

This CL is the first step and the old classes are still left in the code
for now to keep backwards compatibility.
