wayland: apply CSD/SSD changes in the surface configure event

The configure event asks the client to change its decoration
    mode. The configured state should not be applied immediately.
    Clients must send an ack_configure in response to this event.
    See xdg_surface.configure and xdg_surface.ack_configure for
    details.

In particular, ”the configured state should *not* be applied
immediately”.

Instead, treat CSD/SSD changes like all other window dimension related
changes: store the to-be mode in win->configure, and apply it in the
surface configure event.

This fixes an issue where foot incorrectly resized the window when the
server switched between CSD/SSD at run-time.
