Set sensor operation parameter implementation

Set operation parameter to sensor HAL. Possible paramters include
local geomagnetic field, local gravity acceleration, device dock
state, whether device should run in high performance mode, and
if a magnetic field calibration guide is in progress.

Bug: 30958130
Test: Tested with marlin. Modified hal implementation can get local
      geomagnetic field.
