Add firstCountableTopology_induced, Subtype.firstCountableTopology, Inducing.firstCountableTopology, and Embedding.firstCountableTopology. These are pretty literal counterparts of the existing secondCountableTopology_induced, Subtype.secondCountableTopology, Inducing.secondCountableTopology, and Embedding.secondCountableTopology.
