Add locking around waiting for initialization to finish, since calling
dispatch_block_wait from multiple threads leads to undefined behavior.
Initialize RTCUIApplicationStatusObserver earlier to give the
initialization block more time to run on the main thread before
starting to query the application state.

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/.
