TL;DR requesting a fake stream always gives you a fake stream. No magic.
The gUMConstraint `fake: true` should take precedence and if set always
use MediaEngineDefault.
If it is set the state of `faketracks` is passed
on to MediaEngineDefault.
If it is not set, but (any of) audio/video loopback devices are set, the
device enumeration will filter out only those.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

The goal here is to leave creation stuff mostly for JS, so we can
convert it entirely over to a non-threadsafe cycle-collected version
without breaking any existing C++ users.
I didn't do this for a remaining use in nsGlobalWindow.h to avoid
including nsVariant.h all over the place.
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.

Simplifies the structure of MediaManager somewhat. Possible since
MediaManager owns both the SourceMediaStream and the DOMMediaStream.

This lets us separate tracks by ownership like so:
* Input - Owned by the producer of the DOMMediaStream (gUM etc.)
* Owned - Contains Input tracks (per above) or tracks cloned tracks
if this DOMMediaStream is a clone.
* Playback - Contains Owned tracks plus tracks addTrack()ed to this
DOMMediaStream minus tracks removeTrack()ed from this
DOMMediaStream.
