Re: [webrtc-pc] degradationPreference shouldn't have a default at the WebIDL level

The issue is mostly that it has no meaning for an `RTCRtpReceiver`. `scaleResolutionDownBy` is in a similar position.

And really, there's no value in having default values in WebIDL for _anything_ in `RtpParameters`, since you're always expected to do `getParameters` followed by `setParameters`. If a parameter has a default value, `getParameters` should have returned it, and it doesn't need a default at the WebIDL level for that to happen.
