Tomas Gunnarsson 10bd1716fb Revert "Reland "Use non-proxied source object in VideoTrack.""
This reverts commit 2c47235b0ef1c7bc1aeadc7d0e3aed18e131b3c7.

Reason for revert: Downstream issue still doesn't seem to be resolved.

Original change's description:
> Reland "Use non-proxied source object in VideoTrack."
>
> This is a reland of 3eb29c12358930a60134f185cd849e0d12aa9166
>
> This reland doesn't contain the AudioTrack changes (see original
> description) that got triggered in some cases and needs to be
> addressed separately.
>
> Original change's description:
> > Use non-proxied source object in VideoTrack.
> >
> > Use the internal representation of the video source object from the
> > track. Before there were implicit thread hops due to use of the proxy.
> >
> > Also, override AudioTrack's enabled methods to enforce thread
> > expectations.
