Reland of Make QualityScaler more responsive to downgrades. (patchset #1 id:1 of https://codereview.webrtc.org/1880103002/ )
Reason for revert:
Regressed behavior is actually desirable (go down to 360p instead of producing super-bad 720p).

> Revert of Make QualityScaler more responsive to downgrades. (patchset #3 id:40001 of https://codereview.webrtc.org/1830593003/ )

> Reason for revert:
> Speculative revert: want to see if this causes the regression in https://crbug.com/602621

> > Permits going from HD to QVGA in 6 seconds instead of 10. Also adds
