x11: Mark backing_store as NotUseful when creating windows. This can give some performance boost, and save some resources, as there's no reason to keep a copy of an SDL window's contents on the server: most SDL apps are redrawing completely every frame, and the API allows for expose events to tell an app a redraw is needed anyhow. (And compositors are free to ignore this setting if it makes sense to do so, according to the Xlib docs.) Reference Issue #3776.
