Overloads with None still doesn't work for pylance core.

Seems still an issue with classmethod's overloads at least (this is from python/pylance extension):

class classmethod(Generic[_T, _P, _R_co]):
    ...
    @overload
    def __get__(self, __instance: _T, __owner: type[_T] | None = None) -> Callable[_P, _R_co]: ...
    @overload
    def __get__(self, __instance: None, __owner: type[_T]) -> Callable[_P, _R_co]: ...`
    ...

Order of overloads does not matter

If i use it:

def trace_class_method(_classmethod: classmethod[T, P, R_co]) -> classmethod[T, P, R_co]:
    @wraps(_classmethod.__func__)
    def wrapper(_cls: type[T], *args: P.args, **kwargs: P.kwargs) -> R_co:
        method = _classmethod.__get__(None, _cls) # type: ignore[arg-type]
        return _log_trace(method, *args, **kwargs)

    return classmethod(wrapper) # type: ignore[arg-type]

The _classmethod.__get__ doesn't seem to use correct overload.
On top of that there is another issue with return classmethod(wrapper) (could be connected to #3482)

For 1.5.1 method get is missing from stdlib typeshed

Overloads do work, problem is mypy typeshed
