When calling `MediaController.getCommandButtonForMediaItem(MediaItem)` command buttons with custom commands that are not available shouldn't be advertised to the controller when connected to a Media3 session. In contrast, when connected to a legacy session, available commands are not enforced when advertising commands. Similarly, when sending a custom commands that is referenced by a command button for media items, sending is permitted without the command being available. This is required because available commands match to custom actions in `PlaybackStateCompat` of the legacy session. Adding commands for media items to custom action of the `PlaybackStateCompat` would interfere with other use cases. Issue: androidx/media#1474 #cherrypick PiperOrigin-RevId: 683717723
