…mestamps from RTCStats objects., a=testonly

Automatic update from web-platform-tests
Update Blink to use environment clock timestamps from RTCStats objects.

https://webrtc-review.googlesource.com/c/src/+/363946 added a config flag to tell WebRTC to set environment clock timestamps in RTCStats objects (rather then UTC timestamps). This CL set the config flag, and update the code to handle the new timestamps.

This change make all RTCStats timestamps be expressed as Performance time, fixing chromium:369369568.
