Reland of Skip paint property update and visual rect update if no geometry change

Reland of Skip paint property update and visual rect update if no geometry change (patchset #1 id:1 of https://codereview.chromium.org/2792863002/ )

Reland after https://codereview.chromium.org/2791933003/ which fixed the
layout test failures (about overflow recalc).

Also fixed a bug of false-negative of visual rect change in
FindPaintOffsetAndVisualRectNeedingUpdate.h.
