Polynomial pose prediction.

Adds PolynomialPosePredictor. It is not enabled by default in sensord.

I will do a grid search for the best parameters before turning it on.

You can set dvr.predictor_type to 1 and restart sensord to test.

Bug: 35362498
Test: Run predictor_eval to test the numerical and performance. Set dvr.predictor_type to 1 for qualitative testing.
