Implementation of sensor additional 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.
