common: motion_sense: Prevent on/off body from waking up device
Introduce a new flag: BYPASS_FIFO to raise an interrupt to the AP
when an event is sent.
It is not as strong as WAKEUP, as it does not wake up the AP.
BYPASS_FIFO must be set when WAKEUP is set.
It is applied to sync sensor as well as gesture/activity sensor.
