Wayland: Fix resize events before ack_configure

Browse Source 
The surface was resized and the size event was emitted before we had
sent xdg_surface::ack_configure.  If user code then called some GLFW
function that commited the surface, those changes would all get applied
to the wrong configure event.

This postpones size changes until after the ack.
