Review mute/unmute/ended and constraints on RTCRtpReceiver's track.

[jan-ivar]

As per w3c/mediacapture-main#984, we should review mute/unmute/ended and constraints on transceiver.receiver.track.

This spec seems in good shape, with § 9.3 MediaStreamTrack specifying mute from BYE and sRD, unmute from incoming RTP, and ended from stop sending and receiving, and with § 9.3.1 MediaTrackSupportedConstraints, MediaTrackCapabilities, MediaTrackConstraints and MediaTrackSettings covering constraints.

Relevant open issues found:

• #2915
• #2880

This issue had an associated resolution in WebRTC March 26 2024 meeting – 26 March 2024 (Clarify each source is responsible for specifying mute/unmute/ended and constraints behavior):

RESOLUTION: close webrtc-pc#2942 as reviewed and webrtc-pc#2915, open an issue on timing of unmuting on RTC reception

[jan-ivar]

Closing per above.

..., open an issue on timing of unmuting on RTC reception

It seems we already have an open issue that looks related:

• #2880

But I may be wrong, as I confess I didn't fully understand the issue. @youennf if this is insufficient, can you open a new one?
