Reviewed by Jean-Yves Avenard.

Update the WebIDL according https://w3c.github.io/mst-content-hint/#dom-rtcdegradationpreference.
We remove the default value and make degradationPreference optional.

This improves some WPT tests, but we have to mark imported/w3c/web-platform-tests/mst-content-hint/RTCRtpSendParameters-degradationEffect.html as failing for now.
The failing messafge is changing everytime.
