Local geomagnetic field update to sensor Local geomagnetic field strength, declination, inclination information is useful for magnetometer calibration. It also benefits rotation vector sensor implementation as it gives a baseline that aids detecting magnetic field disturbance. Bug: 30958130 Test: Tested with marlin. Modified hal implementation can get local geomagnetic field. Change-Id: I373fe74d5a091a3adb80ff3c61e441edcf5a253b
