Adding volume slider tracker configuration.

A customized SeekableSliderTrackerConfig object is supplied to the
vertical volume slider haptics. The purpose is to decrease the lower
bookend threshold and increase the upper booken threshold. With
this,bookend haptics will correspond to the lower and upper limits of
the volume stream controlled by the volume slider.

Test: atest SystemUITests:VolumeDialogImplTest
Test: manual. Short-press volume keys to reach uppper and lower bookends
  -> verify that haptics are delivered on the true upper and lower
  limits
