[gnome-builder/wip/gtk4-port] plugins/shellcmd: start on runner support

    plugins/shellcmd: start on runner support
    
    This is just a prototype to start on various runner types. It will likely
    change (especially if we can remove IdeRunner from libide-foundry) but
    the goal is to have this working first, then refactor if we have time
    before 43.
