[gnome-shell] windowMenu: Implement new show_menu_for_rect() hook

[Florian Müllner <fmuellner src gnome org>]

    windowMenu: Implement new show_menu_for_rect() hook
    
    Having the full geometry of the menu's source button (if any) will
    allow us to address several misbehaviors of window menus, so use
    that instead of show_menu().
