This is a reland of commit 82617ac51e7825db53451818f4d1ad52b69761fd
The reason for the revert was a downstream use of
`rtc::VideoSinkWants::requested_resolution`, so in this reland we don't
rename this field, it's fine just to rename the one in
RtpEncodingParameters for now.

Add an environment clock timestamp to SenderReportStats and make it visible in rtc_stats_collector.cc. This make it possible to use the pc->GetConfiguration().stats_timestamp_with_environment_clock() flag to decide which timestamp to use when creating a RTCRemoteOutboundRtpStreamStats object.
This CL is the third (and possible the last) of a series of CLs that aim to replace the UTC timestamps in RTCStats objects to Environment clock timestamps. The other CLs where https://webrtc-review.googlesource.com/c/src/+/363946 and https://webrtc-review.googlesource.com/c/src/+/364782.
When Chromium and Google internal uses of RTCStats are updated to set the stats_timestamp_with_environment_clock configuration, the flag can be deleted.

I missed one timestamp in https://webrtc-review.googlesource.com/c/src/+/363946, meaning that the config flag that was added do not yet work for all timestamps in RTCStats objects. The RTCRemoteOutboundRtpStreamStats still has UTC timestamps even if the config flag is set.
I will solve this by saving both an UTC (existing) and env (to be added) timestamp, and then let rtc_stats_collector choose timestamp based on the value of the config flag (just like RTCRemoteInboundRtpStreamStats is done in the 363946 commit).
Before adding the new env_ timestamp I want to make this change. I rename the existing timestamp to show what epoch it uses (NTP or UTC). This will later make it clear which timestamp is which.
So this CL will make no logical change, just renaming members.
I only need to rename the last_sender_report_timestamp_ms, but opted to rename the remote timestamp as well, to be consistent with the naming convention I add in this CL.

This API should not modify the aspect ratio of the frame, e.g. if the
frame is 1280x720 and requested_resolution is 1280x360, the result
should be 640x360, not a streched out 1280x360 frame. The spec version
of this API calls this "maxWidth" and "maxHeight" which is the right
way to think about it rather than a forced width and height.
VideoAdapter continues to be used to apply adaptation restrictions, but
we now make sure to calculate the correct frame size BEFORE applying
restrictions. Prior to this CL, the VideoAdapter was also used to apply
requested_resolution restrictions. This is actually wrong and would
cause strange scaling factors in some cases, e.g. f=1280x720 + r=720x405
would result in 640x360 instead of 720x405. Now we make f=720x405 first
and only adjust further if restrictions or alignments require us to.
Since this is a change in behavior a WebRtcVideoChannelTest is updated.
Encodings integration test is also added, both for aspect ratio (new
behavior) and orientation agnosticism (old behavior still passing).

According to spec, if you ask for three encodings you get three
encodings (duh). But according to legacy code, if you ask for three
encodings AND codec is VP9, then surely you meant a single encoding that
is kSVC where the other encodings influence the scalability mode of the
first encoding.
Standard simulcast support in VP9 was shipped as an opt-in feature where
you have to specify `scalability_mode` and `scale_resolution_down_by` in
order to let WebRTC know that you want to disable the legacy path.
But `scale_resolution_down_by` is not the only way to configure
resolution, there is also the `requested_resolution` code path. This CL
adds standard simulcast support for this code path as well.
Prior to this change, our parameterized test would have passed in VP8
but failed in VP9. With this change the test passes for all codecs.

Below, the encoder_context for the first stream will be reused but
then we only intercept the callback for the stream_idx>0.
Therefore if RegisterEncodeCompleteCallback() is called before the InitEncode(), the first stream will end up with nullptr callback.
To ensure this doesn't happen, restore the callback on the reusable encoder.

A class inheriting SimulcastEncoderAdapter possibly owns the resource.
Since a base class' destructor cannot be called before a child class,
the child class needs to destroy encoders by invoking

reduced-size RTCP, i.e. not prefixing RTCP packets with either a sender report or receiver report has been implemented for a long time but only for video.
This CL adds it for audio as well. This reduces the size of audio NACKs (16 bytes, typically one NACK per packet) sent by not prefixing it with a receiver report (32 bytes).
Other packets are not affected as e.g. transport-cc feedback does not add a RR even though that is technically required.
The effect on NACK can be tested by running Chromium with
--disable-webrtc-encryption --force-fieldtrials=WebRTC-FakeNetworkReceiveConfig/loss_percent:5/
against this fiddle negotiating audio nack:

This is done in case the new source has a different clock source which
might be out of sync with the previous one, leading to timestamp
conflicts.
