Vlad Zahorodnii 0ad4901687 wayland: Provide a way to force xdg surface configure events 
XdgSurfaceClient tries to avoid sending unnecessary configure events,
but in some cases, the compositor has to send one even if the surface
state hasn't changed, for example in response to a set_maximized()
request, etc.

This change introduces a special flag to indicate that the scheduled
event has to be sent no matter what.
