A follow up to stopping speaker playback with a Player decorator from
https://github.com/androidx/media/issues/15.
It looks like we will need to change to using playback suppression to avoid
errors like https://github.com/androidx/media/issues/167, when we don't start
a foreground service.
We may not have this implemented by 1.0, but would like it in the API and it seems to be appropriate.

I don't think it's useful to keep these in numerical order, it makes
more sense to keep them grouped into a 'logical' ordering.
