Wayland: Fix events emitted before ack_configure 

Window iconfication and maximization events were being emitted before
xdg_surface::configure, making it possible for user code to indirectly
commit surface changes from those event callbacks before
xdg_surface::ack_configure.

This postpones those events until after the ack has been sent.

(cherry picked from commit 85f5a51912)
