RequestEncoderFallback, RequestEncoderSwitch and
SetVideoCodecSwitchingEnabledRequest are now all called on the
worker thread. Before, the work already happened on that thread but
WebRtcVideoChannel adapted internally when needed.
With this CL, there are thread checks to make sure that these calls are
always made the same way, we don't need the async invoker and there
are fewer calls out from the encoder thread in VideoStreamEncoder
(reducing the chance of unintentional blocking).

This turned out to be a bit complicated, mostly
related to the tests, but here's what's changed:
* No AsyncInvoker (and avoid ClearInternal) in
WebRtcVideoSendStream (WVSS)
* The reason it was there is due to a "design leak" from
VideoSourceSinkController/VideoStreamEncoder where the former uses
locks in all methods and is unaware of a threading model. That design
affected downstream objects, pushed the need for an async hop into
WVSS and added a lock.
A suggestion was made to address this in a follow-up change, here:
https://webrtc-review.googlesource.com/c/src/+/165684
* All methods in VideoSourceSinkController are now called on a known
and checked sequence and this CL removes the lock. This also makes
checking state consistent (i.e. calling a getter twice in a row on the
same sequence, will always return the same value, avoiding race with
other threads).
* Handling of reporting state changes from the encoder queue to the
VSSC, is done by VideoStreamEncoder.
* VideoSendStreamImpl is still instantiated on the incorrect thread [1]
but has two initialization steps [2]. The second one already runs on
the right thread. Addressing that TODO [1] is something we should do
but it has side effects to consider. For the purposes of this CL
the steps relating to the encoder (setting the sink pointer) have
been moved to [2].

RtpVideoStreamReceiver was forked to RtpVideoStreamReceiver2
recently, so the code that checks for this parameter needs to
be present in the forked location, but it wasn't.
This also enables RtpVideoStreamReceiver2TestH264.InBandSpsPps test
on MSAN, which was another already fixed bug that wasn't ported over
to the recently forked RtpVideoStreamReceiver2.
See webrtc:11595 for information about the fork.
See webrtc:11769 for information about this fmtp parameter.
See webrtc:11376 for the original MSAN issue.

This reverts commit 60c25a303fac85dccb2ccdd9e8d6d71be13b7541.
Reason for revert: Breaks downstream iOS testers.
From an offline discussion, the GN argument is not needed and only
the 3 xctest needs the behavior of that argument. So I am reverting
this one and preparing 2 CLs to properly fix.
Original change's description:
> Reland "Switch from "rtc_ios_xctest_test" to "rtc_test"."
>
> This is a reland of 7a73c772e21983857e46cb4fcedc6cfa3f42c03e
>
> The change to fix the downstream issue is just the switch from
> "test" to "rtc_test" which is a GN template that expands to
> "test".

WebRTC’s Audio Video sync can go in unbounded loop and keep on increasing audio delay if audio packets stop coming in.
The issue happens, if StreamSynchronization::ComputeDelays has:
1. relative_delay_ms = some positive value which causes avg_diff_ms_ > 30ms
2. current_audio_delay_ms < current_video_delay_ms
3. audio_delay_.extra_ms > 0 and video_delay_.extra_ms = 0
To compensate for relative delay, audio_delay_.extra_ms gets incremented every time StreamSynchronization::ComputeDelays is called by RtpStreamsSynchronizer::Process(), which happens every 1sec
RtpStreamsSynchronizer::Process() will try to set the new delay to audio stream by calling syncable_audio_->SetMinimumPlayoutDelay(target_audio_delay_ms);
This ends up calling DelayManager::SetMinimumDelay and update minimum_delay_ms_
But this update has no impact on the value returned by NetEqImpl::FilteredCurrentDelayMs (as there are no audio packets flowing in, hence neteq is not running) which is called next time RtpStreamsSynchronizer::Process(), runs and tried to compute the new audio delay (audio_info→current_delay_ms)
This causes audio delay to be increased in every iteration and it grows unbounded. I guess it will stop growing above 10sec as that is hardcoded max delay in NetEQ.
To avoid this added a check to not adjust delays when no new audio stream has come in.
