    wayland: consider edge constraints in surface configuration
    
    Now that GTK windows have the ability to properly handle
    per-edge tiling constraints, this patch extends GTK's
    internal Wayland protocol to have a proper enum with the
    relevant edge data.
    
    Once this approach is validated, we can think of upstreaming
    this work as an official Wayland protocol extension.
