ee_wayland: Update maximize and fullscreen state after configure

Summary:
If the compositor drops fullscreen or maximize for us the CSD to change
that state would become broken, as ecore_wl2 thought the window state
was whatever we last set it to from the client side.

Update that state on configure event.
