Returns an [`IdentifiedNode`][rdflib.term.IdentifiedNode] for the path (which should be the object of a triple with predicate `sh:path`) and the graph into which any new triples were added.

If not provided, a new graph will be created Returns: A (path_identifier, graph) tuple where: - path_identifier: If path is a [`URIRef`][rdflib.term.URIRef], this is simply the provided path. If path is a [`Path`][rdflib.paths.Path], this is the [`BNode`][rdflib.term.BNode] corresponding to the root of the SHACL path expression added to the graph. - graph: None if path is a [`URIRef`][rdflib.term.URIRef] (as no new triples are constructed). If path is a [`Path`][rdflib.paths.Path], this is either the target_graph provided or a new graph into which the path triples were added.
