Make Media Vibration setting configurable

Add a configuration boolean to control whether or not to display
Media Vibration switch (default: display the switch).
This configuration can then be overriden by OEMs for devices
that don't support media vibration.

Bug: 268657239
Test: make RunSettingsRoboTests ROBOTEST_FILTER=
