Layer/Rectangle improvements (#6247)

Browse Source 
* Use Rectangle for breadcrumbs background.

* Use Rectangle for status bar bg.

* Use Rectangle for dropdown bg.

* Dirty global_element_depth_order invalidates sublayers

* Setting new parent may invalidate depth order

* Support per-instance pointer_events_enabled

* Remove workaround for #6241
