Review mute/unmute/ended and constraints on new VideoTrackGenerator().track

[jan-ivar]

As per https://github.com/w3c/mediacapture-main/issues/984, review mute/unmute/ended and constraints on new VideoTrackGenerator().track.

Mute/unmute is controlled by VideoTrackGenerator's muted attribute.

The track is ended when the writable is closed (nit: the "end" link is wrong):

Constraints are defined in § 2.2.5.2. Constrainable properties.

Everything seems in order. No relevant open issues found.

§ 2.2.5.3. Events and attributes might be problematic (highlighted):

...as it implies rather than specifies functionality, which appears to go against the extension criteria (it also seems unclear what constitutes "any MediaStreamTrack"). What specific functionality was meant to be covered here?
