Keep values related to LegacyPlayerView in attrs_legacy_player_view.xml
and put all values related to LegacyPlayerControlView back in their
original locations. We plan to remove LegacyPlayerView (and
attrs_legacy_player_view.xml) from media3, but will keep
LegacyPlayerControlView - so the separation of the XML files needs to
reflect this split.
