Wayland client: Don't applyConfigure for destroyed surface

Browse Source 
If a window is rapidly hidden and re-shown multiple times, the configure
for a deleted wl_surface may be invoked after a new surface has been
created. This change makes sure we always reset mWaitingToApplyConfigure
before a new wl_surface is created. The superfluous applyConfigure
invocation will then be safely ignored.

Fixes: QTBUG-96464
Pick-to: 6.2
