WINGs/wview_wl: send WME_CONFIGURE to parent on child resize 

On X11, resizing a child window generates a ConfigureNotify event
delivered to the parent. Scroll views rely on this to update scroller
proportions when the content view is resized. On Wayland, wl_resize
never generated this event, so the scroller's documentFullyVisible
flag stayed at 1 (set during initial setup when content was small)
and paintScroller drew only a stippled 'full' indicator instead of
the knob/track.

Fix: when a mapped non-toplevel view is resized, dispatch a
WME_CONFIGURE event to its parent synchronously.
