Introduce alarm and media vibration intensity settings

Introduce toggles and sliders to configure the alarm and media
vibrations in the "Vibration & haptics" settings app.

Also update the multiple intensities configuration flag into a integer,
where the device can specify how many distinct levels are supported.
Follow existing implementation to map the intensities to higher setting
values.
