The lock in TransportFeedbackProxy could cause a dead-lock if audio is included in transport feedback messages, and necessitated a revert: https://webrtc-review.googlesource.com/c/src/+/178100 This CL removes that lock and in fact the entire TransportFeedbackProxy class, and instead sets the observer at construction time. We therefore don't need to guard the observer pointer anymore.
