Spatial Audio: Improve Head-Tracking prediction

1) Add LEAST_SQUARES pose prediction.
Define 3 types of prediction: LAST, TWIST, and LEAST_SQUARES.
Furthermore, add a 4th AUTO prediction type to automatically
choose between the 3 (currently always selects LEAST_SQUARES).

2) Add Verification of pose prediction,
Enabled on userdebug and eng builds.
Prediction checked for 50ms, 100ms, 200ms look-ahead.

3) Add 2 properties for predictor control

audio.spatializer.pose_predictor_type
// Example: 0 == AUTO, 1 == LAST,
//          2 == TWIST, 3 == LEAST_SQUARES

audio.spatializer.prediction_duration_ms
// Example: 50 or 150

4) By default
Use the new LEAST_SQUARES predictor. (Old was TWIST)
Increase prediction_duration_ms from 50ms to 120ms.

Test: adb shell dumpsys media.audio_policy
Test: atest libheadtracking-test
Test: adb shell setprop on properties.
Test: force user / eng compilation modes
