Pipe wakeup sensor events to batterystats

Creating another method in BatteryService to send notifcations from
sensor event connection to BatteryStatsService.

Passing the sensor handle so java code can retrieve a Sensor object and
then query any properties of the sensor from there.

Test: Manually trigger sensor events and check logcat

Ignore-AOSP-First: AIDL method definition not present in AOSP.
