Add support for Python 3.13+ free-threaded builds (PEP 703).

The stable ABI (Py_LIMITED_API) is not compatible with free-threaded python because the limited API headers don't include atomic operations required for thread-safe reference counting, see https://docs.python.org/3/c-api/stable.html. This change disables the stable ABI for free-threaded builds.
