Subject: [PATCH] Avoid using the thread state attribute "use_tracing" in
 Python 3.12 where it was removed from the struct.

See PEP-669 (https://peps.python.org/pep-0669/) and the implementation in https://github.com/python/cpython/pull/103083.
There is more to be done to properly support PEP-669, but this makes it compile.

See https://github.com/cython/cython/issues/5450
