ScopedTaskSafety simplifies usage of PendingTaskSafetyFlag,
so this CL also includes ToQueuedTask support for ScopedTaskSafety
and test updates.
This is following up on feedback in the following CL:

This reduces locking on the decoder thread and moves all stats
management to the worker thread, which also avoids contention between
querying for these stats and the threads where the media processing happens..

This offloads the decoder thread with managing histograms,
moves the management over to the thread on which they're queried.
This will allow us to remove more locking from the decoder threads
and avoid contention when querying for stats.

Remove dependency on ProcessThread.
Instead RtpStreamsSynchronizer uses the worker thread
and makes callbacks on the same thread. That in turn
simplifies locking for VideoReceiveStream2, which we'll
take advantage of later.

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/

Call is instantiated on what we traditionally call the 'worker thread'
in PeerConnection terms. Call statistics are however gathered, processed
and reported in a number of different ways, which results in a lot of
locking, which is also unpredictable due to the those actions themselves
contending with other parts of the system.
Designating the worker thread as the general owner of the stats, helps
us keeps things regular and avoids loading unrelated task queues/threads
with reporting things like histograms or locking up due to a call to
GetStats().
This is a reland of remaining changes from https://webrtc-review.googlesource.com/c/src/+/172847:
This applies the changes from the above CL to the forked files and
switches call.cc over to using the forked implementation.
