Extract input device vibrators code from VibratorService

This code will also be migrated to VibratorManagerService, to give
preference to input devices over the devices vibrators when the user
setting enables it.

This need to remain a server-side code so permissions/setting will be
applied to system vibrations even when they are redirected to input
devices (including vibration scaling).
