RTCVideoFrame is an ObjectiveC version of webrtc::VideoFrame, but it currently contains some extra logic beyond that. We want RTCVideoFrame to be as simple as possible, i.e. just a container with no extra state, so we can use it as input to RTCVideoSource without complicating the interface for consumers.
