HID dynamic sensor: add support to three types of sensor

Browse Source 
Implemented HID dynamic sensor using linux hidraw driver and
HidUtils. Support the following cases:

1) HID Sensor spec defined accelerometer, gyroscope, magnetometer
   and orientation (quaternion).
2) Android defined type sensors (HID sensor custom type): ambient
   temperature, barometer, light and heart rate sensor.
3) Android custom type sensor (based on HID sensor custom type).

Test: run tests/examples in test/
Test: test with a USB HID hardware (launchpad sensor) and marlin
