[issue38006] Crash in remove() weak reference callback of weakref.WeakValueDictionary at Python exit

[Pablo Galindo Salgado]

In particular, this was not happening before because the function type did not implement tp_clear:

https://github.com/python/cpython/blob/3.7/Objects/funcobject.c#L615

The new implementation of tp_clear without checks is allowing this to happen.
