Support RGB frames in RTCCVPixelBuffer

Browse Source 
In addition to NV12 frames, also support cropping/scaling RGB frames and
converting RGB frames to i420.

This CL also removes the hardcoding of pixel format in
RTCCameraVideoCapturer. Instead, use the first available format for the
output device that our pipeline supports.
