Re: [webrtc-pc] scaleResolutionDownBy validation steps are inconsistent, browser interop issues (#2873)

> today there is a preference towards not specifying scaleResolutionDownBy

This preference has to do with a bug in adaptation logic when scaleResolutionDownBy being specified or with specifying it being an opt-out of legacy VP9 kSVC mode.

So to be fair, the preference basically has to do with browser bugs and historical reasons rather than sensible things. But I still think there is value in allowing the app to not specifying scale and getting 4:2:1 so that applying the same parameters at init and at setParameters have the same effect.
