Revert "Reduce locking in VideoReceiver and check the threading model."

This reverts commit c75f1e45093a8d5cc62937c7708b87aa5c5bf0b0.

Reason for revert: Breaking internal project

Original change's description:
> Reduce locking in VideoReceiver and check the threading model.
> 
> Note: This is a subset of code that was previously reviewed here:
>   - https://codereview.webrtc.org/2764573002/
> 
> * Added two notification methods, DecoderThreadStarting() and DecoderThreadStopped()
>   * Allows us to establish a period when the decoder thread is not running and it is
>     safe to modify variables such as callbacks, that are only read when the decoder
>     thread is running.
>   * Allows us to DCHECK thread guarantees/correctness.
>   * Allows synchronizing callbacks from the module process thread and have them only
>     active while the decoder thread is running.
>   * The above, allows us to establish two modes for the thread,
>     single-threaded-mutable and multi-threaded-const.
>   * Using that knowledge, we can remove |receive_crit_| as well as locking for a
>     number of member variables.
> * Removed |VCMFrameBuffer _frameFromFile| (unused).
> * Clean up several of my TODOs
>
