Direct report mode support in sensor service and client

Added SensorDirectConnection to represent the direct channel.
The life-cycle is similar to that of SensorEventConnection.
Modified SensorDevice and SensorDeviceTreble to support new
HAL API. Added support in SensorManager, SensorService, binder
classes. Also added related helper functions in Sensor and dumpsys
support in SensorList.

Test: manual test with demo app
