    Implement all_dep_attrs() more efficiently for get_attr

    Override the default implementation of all_dep_attrs() (which calls
    dep_attrs() in a loop). This makes all_dep_attrs() for GetAtt and its
    arguments as efficient as dep_attrs(), even if we only need the data for a
    single resource (as in convergence after we update a resource).
