Don't compute occlusion when window with hidden parent is hidden/shown. A window with a hidden parent is not painted on the screen. Calling Hide() or Show() on it can't immediately affect occlusion and should therefore not cause occlusion states to be recomputed. This optimization is useful for when we hide a WebContentsViewAura. When we hide a WebContentsViewAura, Hide() is called on child RenderWidgetHostViewAura. There is no reason to recompute occlusion when that happens.
