Update PowerHAL wrapper support checking behavior 

- Updates support checks to check status for UNKNOWN_TRANSACTION
- Adds PowerHintSessionWrapper class to check support on session methods
- Ensures that wrapper methods check the HAL version number for support
- Adds macros to cache returned wrapper call support status
