Respect the smooth scrolling setting in LayerScrollableArea.
This was previously done in http://crrev.com/214953004 but reverted due to
http://crbug.com/383946. With http://crrev.com/831393003 it should be safe to
re-land. (This is also needed for http://crbug.com/417782 because everything
will go through the LayerScrollableArea path.)
