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.

Fix a few known issue in sensor framework
* Resolve issues pointed out by API Consul:
. Privacy concern about sensor UUID
. Callback name consistency,
. A few document error and typo.
* New API to tell app if the sensor system support dynamic sensor
discovery.
* Added API to make dynamically connected sensor directly
identifiable.
* Explicitly indicate sensor additional information support for a
sensor

Implementation of sensor additioanl info report
This implements a mechanism for sensor hardware/HAL to deliver additional information beside sensor
readings to application. It includes internal temperature reading, untracked delay of sample,
location and pose of sensor device placement in phone frame, etc. This is also a very expandable
frame to account for future need.

Note: sensor additional information report used to be called sensor meta data.
