SurfaceFlinger: clear LayerHistory on first touch

 - Restructure the code in RefreshRateConfigs to be able to clear
   LayerHistory frames on the first touch event. Without this change we
   clear the history on every frame as long as the touch timer hasn't
   expired.
 - Add log prints for debugging

Test: Play 24fps video in YouTube PIP mode and rotate the device - no jank
Test: Chrome playing video - no refresh rate switching
Test: Hide/Show keyboard when inputting text
Test: Running Hay Day and observing refresh rate
