Add VibrationAttributes

Added a class for attributes of vibrations, to gradually replace usage
of AudioAttributes in haptics context. Refactored VibrationService and
related classes to use VibrationAttributes, converting AudioAttributes
to VibrationAttributes and back as necessary

Test: manual. Since it's a refacroring, everything should work as before
