feat(topology/bases): Topological basis of a product. (#7753) Given a family of topological spaces X_i with topological bases T_i, this constructs the associated basis of the product topology. This also includes a construction of the tautological topological basis consisting of all open sets. This generalizes a lemma from LTE.
