wayland: Fix xdg-output v3 support

The xdg_output.done event is deprecated in xdg-output v3, so clients
need to rely on the wl_output.done event instead.

However, applying the changes on the fist wl_output.event when using
xdg-output v3 may lead to an incomplete change, as following xdg-output
updates may follow.

Make sure we apply xdg-output events on wl_output.done events with
xdg-output v3.
