[IntersectionOptimization] Improve and fix cached rect invalidation

• Move invalidation from
  ObjectPaintInvalidator::InvalidateDisplayItemClient to
  PaintInvalidator::InvalidatePaint because the former doesn't
  invalidate LayoutObjects that don't paint while these LayoutObjects
  can still observe intersection based on layout.
• Rename InvalidateCachedRectsIfNeeded to
  InvalidateCachedRectsIfPaintPropertiesChange() because it only
  handles paint property changes but not local layout changes.
• Skip scroll optimization if the cached rect is invalidated for other
  reasons.
