gh-132775: Add _PyCode_ReturnsOnlyNone() (gh-132981)
The function indicates whether or not the function has a return statement.

This is used by a later change related treating some functions like scripts.

gh-127266: avoid data races when updating type slots (gh-131174)
In the free-threaded build, avoid data races caused by updating type slots
or type flags after the type was initially created.  For those (typically
rare) cases, use the stop-the-world mechanism.  Remove the use of atomics
when reading or writing type flags.  The use of atomics is not sufficient to
avoid races (since flags are sometimes read without a lock and without
atomics) and are no longer required.

gh-132942: Fix races in type lookup cache (gh-133032)
Two races related to the type lookup cache, when used in the
free-threaded build.  This caused test_opcache to sometimes fail (as
well as other hard to re-produce failures).

gh-132775: Add _PyModule_GetFilenameObject() and _PyModule_GetFilenameUTF8() (gh-132979)
They are derived from the existing `PyModule_GetFilenameObject().

They are used by a later change related to pickle and handling __main__.

gh-131586: Avoid refcount contention in some "special" calls (#131588)
In the free threaded build, the `_PyObject_LookupSpecial()` call can lead to
reference count contention on the returned function object becuase it
doesn't use stackrefs. Refactor some of the callers to use
`_PyObject_MaybeCallSpecialNoArgs`, which uses stackrefs internally.

This fixes the scaling bottleneck in the "lookup_special" microbenchmark
in `ftscalingbench.py`. However, the are still some uses of
`_PyObject_LookupSpecial()` that need to be addressed in future PRs.
