chore(Topology): improve API and golf (#23633) Deprecate isTotallyDisconnected_of_isClopen_set because it encourages people to prove the weaker TotallyDisconnectedSpace rather than the stronger TotallySeparatedSpace. Prove IsTopologicalBasis.of_isOpen_of_subset and use it to golf IsTopologicalBasis.insert_empty and PrespectralSpace.of_isTopologicalBasis.
