GH-133789: Fix unpickling of pathlib objects pickled in Python 3.13 (GH-133831)
In Python 3.13 (but not 3.12 or 3.14), pathlib classes are defined in
`pathlib._local` rather than `pathlib`. In hindsight this was a mistake,
but it was difficult to predict how the abstract/local split would pan out.
In this patch we re-introduce `pathlib._local` as a stub module that
re-exports the classes from `pathlib`. This allows path objects pickled in
3.13 to be unpicked in 3.14+

gh-140153: Fix Py_REFCNT() definition on limited C API 3.11-3.13 (GH-140158)
(cherry picked from commit 728d239e57)
Co-authored-by: Victor Stinner <vstinner@python.org>
The previous `Py_REFCNT(x) == 1` checks can have data races in the free
threaded build. `_PyObject_IsUniquelyReferenced(x)` is a more conservative
check that is safe in the free threaded build and is identical to
`Py_REFCNT(x) == 1` in the default GIL-enabled build.
