REGRESSION (STP 239-240): MediaStreamTrack DataCloneError: The object can not
be cloned

Reviewed by Eric Carlson.
We add a quirk that allows to serialize MediaStreamTrack via postMessage.
Basically, any track that is not in the transfer list is cloned and the clone
is added to the transfer list.
This ensures that the serialized track is not stopped as part of postMessage.
We enable this quirk for Zoom.
This quirk is only enabled for document's contexts, not workers, since this is
sufficient to unbreak Zoom.
