The current ObjC HW encoder is implemented as a C++ webrtc::VideoEncoder. We then wrap it two times in the following way: webrtc::VideoEncoder -> RTCVideoEncoder -> webrtc::VideoEncoder. This was originally done to minimize the code diff when landing the injectable encoder. This CL removes the first wrapping and implements the ObjC HW encoder as a RTCVideoEncoder directly. Similarly, the decoder is implemented as a RTCVideoDecoder directly. Based on andersc@ CL: https://codereview.webrtc.org/2978623002/.
