During the PEP 695 implementation at one point I madeTypeVar.__name__ return garbage, and all of test_typing passed.So I decided to add a few more tests. In the process I discovereda minor incompatibility from the C implementation of TypeVar:empty constraints were returned as None instead of an empty tuple.

I started out trying to backportpython/cpython#104571, butrealized that it makes sense to backport CPython's whole TypeVarTestsclass since we now have our own implementation of TypeVar.I dropped test_var_substitution and test_bad_var_substitutionsince they rely on the internal __typing_subst__ method, and thetype substitution logic is generally very hard to get preciselythe same across versions.
