Create Sensors HAL 2.0 Default Implementation
Auto-generated default implementation for Sensors HAL 2.0 via
hidl-gen and cleaned up formatting.
Modifies Android.bp for binderized HAL implementation which includes:
- Adding service.cpp
- Adding android.hardware.sensors@2.0-service.rc
android.hardware.sensors@2.0-service.rc was copied and updated from
the sensors@1.0 default implementation.
Bug: 111070257
Test: Builds
Change-Id: I6a939511ff6b4011cfe95bd26c3093ad18f26f5a
