Summary: Get the physical size directly from the always available output device interface instead of saving an additional copy in the abstract wayland output class. There is some ambiguity with orientation and naming that needs to be cleaned up when output orientation is reworked. Test Plan: Nested Wayland, Drm, virtual backends tested.
