  [GStreamer][WebRTC] replaceTrack support
https://bugs.webkit.org/show_bug.cgi?id=252820

Reviewed by Xabier Rodriguez-Calvar.

In the GStreamer WebRTC backend `sender.replaceTrack()` is now supported. Under the hood, the
outgoing media source now has an input-selector just after the mediastreamsrc element. This allows
us to toggle between a mediastreamsrc and a fake source, eg, when replacing the track with null.
