Change names of builtin types exposed in the types module

Commencez par examiner les types intégrés exposés via le module types, leurs valeurs actuelles de module, name et qualname, ainsi que les PRs associés gh-100130, gh-100142, gh-100405 et gh-100406. Reproduisez l’exemple de pickling de types.ClassMethodDescriptorType ; c’est terminé lorsque les noms et les métadonnées exposés correspondent et que ces types peuvent être sérialisés par pickling.

Some builtin types (like int, range, map) are exposed in the builtins module under their names. int.__name__ is "int" and int.__module__ is "builtins". getattr(sys.modules[int.__module__], int.__name__) is int

Other builtin types are exposed in the types module, but their __module__ attribute is still "builtins", and their __name__ attribute is different from the name under which they are accessible in the types module. The relation between names is not obvious, when you see <class 'builtin_function_or_method'>, it is hard to defer that it is types.BuiltinFunctionType.

As result, these types cannot be pickled:

>>> pickle.dumps(types.ClassMethodDescriptorType)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
_pickle.PicklingError: Can't pickle <class 'classmethod_descriptor'>: attribute lookup classmethod_descriptor on builtins failed

I propose to change attributes __module__, __name__ and __qualname__ of all builtin types exposed in the types modules so that they will match names under which they are accessible.
