`types._GeneratorWrapper` is no longer consistent with `types.GeneratorType`/`types.CoroutineType`

Bug report

Bug description:

types.coroutine() uses _GeneratorWrapper as a wrapper for generator iterators in cases where the callable object is not a user-defined function (but is, for example, a generator function compiled via Cython/Nuitka). However, the implementation has not been updated for 11 years and therefore does not provide certain properties, such as:

• GeneratorType.gi_suspended (Python ≥3.11, python/cpython#30633)
• CoroutineType.cr_suspended (Python ≥3.11, python/cpython#30633)
• CoroutineType.cr_origin (Python ≥3.7, python/cpython#5250)

As a result, the objects returned by the new function do not look exactly like types.GeneratorType/types.CoroutineType, which in particular makes them incompatible with the inspect.getgeneratorstate() and inspect.getcoroutinestate() functions:

>>> from inspect import getcoroutinestate, getgeneratorstate
>>> from types import coroutine
>>> def generator_function():
...     return
...     yield  # generator definition
>>> @coroutine
... def coroutine_function():
...     return generator_function()
>>> gencoro = coroutine_function()
>>> getgeneratorstate(gencoro)
Traceback (most recent call last):
AttributeError: '_GeneratorWrapper' object has no attribute 'gi_suspended'
>>> getcoroutinestate(gencoro)
Traceback (most recent call last):
AttributeError: '_GeneratorWrapper' object has no attribute 'cr_suspended'

Interestingly, there was already an attempt to add *_suspended in #133373 (see https://github.com/python/cpython/issues/133372#issuecomment-2849166854), but the PR was closed in favor of removing the TODO comment, and this side issue was apparently overlooked.

Commencez par les lignes 255-289 de Lib/types.py, puis examinez inspect.getgeneratorstate() et inspect.getcoroutinestate(), que le rapport identifie comme des points d’entrée affectés. Comparez les attributs exposés par le wrapper avec GeneratorType et CoroutineType ; le travail est terminé lorsque les deux fonctions inspect fonctionnent pour les objets encapsulés et que les propriétés de suspension et d’origine indiquées sont cohérentes.
