PlaybackNotificationManager should show play button in ENDED state

Browse Source 
- This brings it in line with PlayerControlView. The play action is displayed
instead, and pressing it seeks to the default position of the current window.
- Do the same for MediaSessionConnector
- Add support for PlaybackPreparer consistent with PlayerControlView

Issue: #5072
