Add AOSP Geomag and Game Rotation, and Gravity
Providing AOSP software implementation of Geomag Rotation Vector, Game
Rotation Vector and Gravity sensors for platforms that does not have
hardware implementation of these sensors but do have primitive sensors
(accelerometers, gyrometers and magnetometers).
Previously, AOSP Gravity sensor is enabled only when all primitive sensors are
available. This is changed so that AOSP Gravity will be available even
no magnetometer is in the device.

use quaternions instead of MRPs
also use correct time propagation equation
disable the fused sensors when gyro is not present since
they were unusable in practice.
