device/vibrator: Add contextual haptics feature

Browse Source 
Add capability for vibrator HAL to detect whether the device is face-up
and adjust/scale haptic alerts to avoid loud and startling buzzing when
there is no case on the device. Added global compile-time disable that
can be set in the environment.
