Move TextTrackContainer::updateSizes to the layout-side

This method is only called from the corresponding LayoutObject
(LayoutTextTrackContainer), so move it and its state there instead.
When the text track container has been properly separated from the media
controls it should be possible to simplify this further by doing this in
the media element's layout object.
