Evan Shrubsole 096ad02c02 Revert "Fix race between enabled() and set_enabled() in VideoTrack."
This reverts commit 5ffefe9d2d743c66f8a8bcbc5ad9662a3138840a.

Reason for revert: Breaks Chromium Android browser tests on fyi bots.

Original change's description:
> Fix race between enabled() and set_enabled() in VideoTrack.
>
> Along the way I introduced VideoSourceBaseGuarded, which is equivalent
> to VideoSourceBase except that it applies thread checks. I found that
> it's easy to use VideoSourceBase incorrectly and in fact there appear
> to be tests that do this.
>
> I made the source object const in VideoTrack, as it already was in
> AudioTrack, and that allowed for making the GetSource() accessors
> bypass the proxy thread hop and give the caller direct access.
>
> Bug: webrtc:12773, b/188139639, webrtc:12780
