Rename those two function to better name alignment with AddDirectListener and AddDirectTrackListener.

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 notify about a created TrackUnionStream track (and since it was
created, we can notify when it ends), even though it has been blocked from main
thread.

Rename StreamBuffer to StreamTracks. We still need a place to keep the track information in every MediaStream, even the StreamBuffer::Track::mSegment is empty.

It wasn't clear which TrackID should be passed to MediaInputPort::BlockTrackId(); source or destination.

Calculating a principal when adding a track is easy - just combine the new
track principal into the stream's principal.
When removing a track it's a bit trickier. The DOMMediaStream has to wait until
the MediaStreamGraph has removed the track from the underlying playback stream.
We do this by letting the MediaStreamGraph return a Pledge (single threaded
Promise) when blocking a track in a stream (the way we end removed tracks).
The pledge gets passed to the MediaStreamGraph and when the block has been
applied it is passed back to the main thread where it is finally resolved
and the DOMMediaStream may recompute its principal once all outstanding
track removals have been applied.

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.
