wayland: Notify actively of xwayland window/surface associations

Browse Source 
Instead of scheduling a meta_later, keep track of the unassociated
windows, and look for matches as soon as the MetaWaylandSurface is
created on our side.

This will ensure the surface is given the Xwayland role before receiving
the first wl_surface.commit.
