[webrtc-pc] webrtc-pc does not specify what level of support is required for RFC 7728 (RTP pause) (#2735)

docfaraday has just created a new issue for https://github.com/w3c/webrtc-pc:

== webrtc-pc does not specify what level of support is required for RFC 7728 (RTP pause) ==
webrtc-pc has support for simulcast paused, which RFC 8853 says requires support for RFC 7728, at least in an answer:

"An answerer that receives an offer without RTP stream pause/resume
   capability MUST NOT mark any simulcast streams as initially paused in
   the answer."

However, RFC 7728 allows partial implementation; there are 8 different "profiles" (that are negotiated with a=rtcp-fb:ccm pause config=\<number\>):

https://datatracker.ietf.org/doc/html/rfc7728#section-9

webrtc-pc probably ought to specify the minimum level of support for RFC 7728.
