Fixes a problem with multiple Player instances created for local video
playback, on the focus of a video conference (which also lead to multiple
Components and renderers being used), which sometimes caused the videos
on the focus' interface to freeze.

Prevents MediaStreamMediaDeviceSession from creating local
Player instances, instead reuses the Player from the
VideoTranslatorMediaDevice's wrapped VideoMediaDeviceSession.

Makes VideoTranslatorMediaDevice a VideoListener of its wrapped
VideoMediaDeviceSession, forwarding all received events to all of its
MediaStreamMediaDeviceSession's.
