Added extra update for CC button visibility

I think this could actually be in MediaControls::closedCaptionTracksChanged(), but I'm not sure if other ports are affected by the bug

This seems like the correct default behavior, so I think it belongs in the base class. Any port that does not want this behavior can override and not call the base method.

Nit: English grammar correction
"as there are no caption tracks"

Thanks for moving this to the base class! I think we should do as much as possible there and leave ports to override it if they disagree (as Eric says).

Some of the new checks appear to fail on EFL port. I'm not sure why yet:
