This is mainly:
- Fix refcount access macro
- Hide all the Dynamo code that needs update as usual
- Add _PyWeakref_ClearRef as an extern provided by CPython. Including the pycore header that defines it would require raw c include shenanigans that I don't think are worth it.
This allows to build both with regular and nogil version of cpython. Both
Note that this requires the 3.13 branch at least past [d3094744d40de2deefbda9b1996d5029c9ebf0b0](d3094744d4) which we need for mimalloc include and weakref function being exposed.
debug-only issues in pybind11 with PyMem_MALLOC vs PyObject_MALLOC being should be synced either by updating pybind or cpython. @colesbury I can send a PR to ifdef the proper use in pybind if you think that this is the best solution here?
