Revert "Remove playout delay lock."

This reverts commit c623495fd1ff90aada0eb625af91ec17843fefd0.

Reason for revert: Need to look into failure in remoting_unittests in Chrome (Webrtc/ConnectionTest.SecondCaptureFailed/0). It looks like the order FrameBuffer2 calls into VCMTiming while receiving frames and updating playout delay values, needs to be synchronized better.

Original change's description:
> Remove playout delay lock.
> Now update the playout delay and related stats on the worker thread.
> 
> This was previously reviewed here:
> https://webrtc-review.googlesource.com/c/src/+/172929/
> 
> With the exception of reducing unnecessarily broad
> lock scope in one function in rtp_rtcp_impl.cc
> and added comments in rtp_streams_synchronizer.h
>

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
