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+

Update `validate_abstract_methods` in `test_collections.py`
The test for missing abstract methods in `validate_abstract_methods` incorrectly attempted to instantiate the generated class `C` with an argument (`C(name)`), which always raises a `TypeError: C() takes no arguments`. Although the test originally passes, it passes for the wrong reason.
This change makes the test correctly validate the enforcement of abstract methods in ABCs.
