Reviewed by Eric Carlson.

UserMediaCaptureManagerProxy keeps sources alive until destroyed.
It is destroyed when its GPUConnectionToWebProcess is destroyed, which can take some time, given it is ref counted.
To be more proactive, we now close the UserMediaCaptureManagerProxy when GPUConnectionToWebProcess loses its IPC connection.
This stops capture sources quickly, we then close the VideoFrame Object heap so that VideoFrames gets disposed quickly.
