This let's us use FindOwnedDOMTrack before the TrackID in mOwnedStream
is known.
This is necessary for a stream clone with multiple tracks whose original
TrackID is the same.

For original tracks, the input TrackID is the same as in its
owned stream.
For cloned tracks, the input TrackID comes from the original track,
since no guarantees about TrackIDs in a cloned DOMMediaStream's owned
stream can be given
(imagine e.g., `new MediaStream([trackID1FromStreamX, trackID1FromStreamY]).clone()`).

This lets a MediaStreamTrack communicate with its source/producer on the
main thread. It's for now used for stopping a track at the source and
retrieving some metadata, but it could also be a link between actual
sinks of a track and the source, to for instance let the source optimize
by scaling down the resolution when all sinks want lowres-video.

Without this, HTMLMediaElement cannot see that the camera stream contains
video so it won't hold the screen wake lock.

This allows us to initiate a DOMMediaStream into three states:
* One that has input, owned and playback streams, for data producers
like gUM or RTCPeerConnection.
* One with owned and playback streams, for cloned DOM streams.
If a cloned DOM stream has an empty input stream connected to its
owned stream, both are regarded as not having current data.
* One with only a playback stream, for when it has been created with the
default constructor from JS. Its track set can only be changed by
addTrack() and removeTrack() which when called only affect mPlaybackStream.

Other modules than MediaTrackLists may want to receive updates on a
DOMMediaStream's track set. This moves the MediaTrackListListener out of
the MediaTrackList class into DOMMediaStream as a general interface.
The logic for adding MediaTracks to the MediaTrackList when
MediaStreamTracks are added or removed from a DOMMediaStream is moved to
HTMLMediaElement as this fits the model better - HTMLMediaElement is the
owner of the MediaTrackLists.

A DOMMediaStream's owned stream is piped from the input stream which is
under the control of the DOMMediaStream's owner/producer (like
captureStream or gUM). When producers like these create new tracks after
the stream has already been created (the initial set should be available
to JS synchronously), it is nice if the DOMMediaStream picks them up
automatically and create the corresponding MediaStreamTracks.
The OwnedStreamListener added here does just that; creates an owned
MediaStreamTrack when a track appeared in the stream that didn't already
have a MediaStreamTrack.
It also moves the logic for ended tracks from the PlaybackStreamListener
to the OwnedStreamListener as we previously would see a track end in the
playbak stream after removeTrack() and that would be interpreted as the
track ending at the source.
