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
