Add unit tests for RTCCVPixelBuffer and ObjCVideoTrackSource.
This CL also fixes a couple of bugs found in the toI420 method for RTCCVPixelBuffers backed by RGB CVPixelBuffers. Bug: webrtc:9007 Change-Id: I19ab8177f4b124a503cfda9f0166bd960f668982 Reviewed-on: https://webrtc-review.googlesource.com/64940 Commit-Queue: Anders Carlsson <andersc@webrtc.org> Reviewed-by: Kári Helgason <kthelgason@webrtc.org> Cr-Commit-Position: refs/heads/master@{#22656}
