Performance test for MotionPredictor
The motion prediction is needed when we are trying to achieve the
smallest possible end-to-end touch latency. The API is designed to be
running directly inside the UI thread, while processing touch.
Therefore, it's important for this class to be fast.
To monitor regressions in the performance of this class, introduce the
performance tests.
