Sensors: Add property for storing sensor init log

ash_logger is to enhance debug mechanism when sensor init.
To enable this debug mechanism, set persist.vendor.debug.ash.logger 1
and persist.vendor.debug.ash.logger.time to proper time.
Sensor init log will be in /data/vendor/sensor/log/.

Bug: 129454044
Test: Build and flash vendor image. Check ash_logger can work.
