[gnome-shell] search: remove SearchProvider base class

    search: remove SearchProvider base class
    
    This is causing more confusion than anything else these days; the DBus
    API is properly documented now and that's what people are expected to
    use, the rest are implementation details we're not interested in
    exposing.
