Instead of relying on special values of edge constraints, this patch adds an internal-only gdk_window_supports_edge_constraints() function that by default returns FALSE, and is implemented by GdkWindowWayland and GdkWindowX11. This way, we can properly detect server-side support for this feature and adapt accordingly. https://bugzilla.gnome.org/show_bug.cgi?id=783669
