Fix fake mouse move event on scroll 

We made LayoutObject::previousPaintInvalidationRect() private but
DeprecatedPaintLayerScrollArea is a friend of LayoutObject, so missed
the change. This caused incorrect fake mouse move event on composited
scroll.

Will fix the friend access issue in
https://codereview.chromium.org/1306993002/.
