LiveDisplayTile: Refresh state after livedisplay initialization

 * SystemUI starts earlier than LiveDisplayConfig initialized, so
   there's no easy way to determin whether to make it available.
 * Instead, receive broadcast incicating initialization completed from
   LiveDisplayService and gray out on desire.
 * Outdoor mode gets fixed by the way.
