This reverts commit fb0dca6c055cbf9e43af665d3c437eba6f43372e. Reason for revert: Speculative revert due to failing stats test in chromium. Possibly because the chromium test expected the metrics to not be supported, and now they are. Reverting just to unblock the webrtc roll into chromium. Original change's description: > Wire up non-sender RTT for audio, and implement related standardized stats. > > The implemented stats are: > - https://www.w3.org/TR/webrtc-stats/#dom-rtcremoteoutboundrtpstreamstats-roundtriptime > - https://www.w3.org/TR/webrtc-stats/#dom-rtcremoteoutboundrtpstreamstats-totalroundtriptime > - https://www.w3.org/TR/webrtc-stats/#dom-rtcremoteoutboundrtpstreamstats-roundtriptimemeasurements > > Bug: webrtc:12951, webrtc:12714 > Change-Id: Ia362d5c4b0456140e32da79d40edc06ab9ce2a2c > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/226956 > Commit-Queue: Ivo Creusen <ivoc@webrtc.org> > Reviewed-by: Henrik Boström <hbos@webrtc.org> > Reviewed-by: Harald Alvestrand <hta@webrtc.org> > Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#34861} # Not skipping CQ checks because original CL landed > 1 day ago.
