Debounce onSetMusicInfo/onSetMusicState calls

Browse Source 
When music player switchs a song, multiple notifications(around 5 in my
test) are sent to NotificationListner, during this,
MediaControllerCompat does not always get the music info we need, the
music info and state seem randomly combined previous song and current
one.

To avoid unnecessary music info updates, debounce
onSetMusicInfo/onSetMusicState calls, so only the last music info and
state are sent to the device.
