Re: [webrtc-pc] Don't let offers to receive simulcast overwrite existing [[SendEncodings]] (#2758)

Having SRD toggle the `active` attributes would create more races like we're trying to remove in https://github.com/w3c/webrtc-pc/issues/2737 I fear.

This is already invalid in JSEP O/A. An answer must stay within the envelope of an offer AFAIK.

I don't think so. This PR isn't modifying any answer behavior.
