[PE] Make NeedsOverflowControlsClip() more accurate

Previously the function was a static function which didn't know the
current paint offset so was unable to calculate the accurate pixel
snapped border box rect, so used a conservative border box rect which
caused some unnecessary OverflowControlsClip() whose change of
existence was not updated.

Now make it a method of FragmentPaintPropertyTreeBuilder to return
the accurate needs, so the change of needs is covered by existing
SetNeedsPaintPropertyTreeUpdate conditions.
