Split ring and notification vibration settings

Synchronize settings between sound and accessibility menus

Bug: 116172311
Test: See accessibility vibration settings - ring and notification
settings sould be separate. Try changing vibration settings in sound and
accessibility menus - the settings should stay in sync.
