This could confuse listeners, since non-direct listeners would see more
data than their direct counterparts.

There was a race where ending the track before removing the direct listener here,
allowed the source to append more data (notifying the direct listener)
after the consumer had been notified of the ending track.

Now everything is ready. We can make NotifyQueuedTrackChanges only triggered by TRACK_EVENT_CREATED and TRACK_EVENT_ENDED without breaking anything. Also we make TrackUnionStream no longer copying data in video case.

This can reduce the include header dependency. MediaStreamVideoSink will inherit from DirectMediaStreamTrackListener. But we can't use forward declaration on MediaStreamListener because the usage of nsTArray<RefPtr<MediaStreamVideoSink>>.

This means that when a MediaStreamListener is added to a stream, we'll call
NotifyQueuedTrackChanges with TRACK_EVENT_CREATE for all tracks that already
exist.
Likewise, we'll call NotifyQueuedTrackChanges with TRACK_EVENT_ENDED for all
tracks that exist and have ended.
This fixes potential race conditions where a track was created and/or ended
before the listener was asynchronously added.

This lets us know the track's TrackID in the destination stream before
the input port has been processed.
For sanity we only allow mapping to a destination TrackID if the
destination stream does not have any TRACK_ANY input ports already
assigned to it as that can cause intermittent TrackID collisions.

TrackUnionStream guarantees that TrackIDs are maintained if no tracks
have claimed them before.
In the gUM case, we have a SourceMediaStream which we wholly own (the
DOMMediaStream's Input stream), piped into a TrackUnionStream which
no-one external is able to add tracks to (the DOMMediaStream's Owned
stream) - addTrack()ed tracks are added to the DOMMediaStream's Playback
stream.
The MediaStreamTracks being enabled/disable refer to a TrackID in the
DOMMediaStream's Owned stream.
Alas, we don't need to forward a track's enabled state, we can just do
it on the source.
