`_overlapped` module cannot be imported without socket support

Bug report

Bug description:

To reproduce, boot Windows 11 into minimal safe mode and run this

import asyncio

It causes this error

Traceback (most recent call last):
  File "C:\projects\asyncio_test_safe_mode.py", line 1, in <module>
    import asyncio
  File "c:\python\Lib\asyncio\__init__.py", line 42, in <module>
    from .windows_events import *
  File "c:\python\Lib\asyncio\windows_events.py", line 8, in <module>
    import _overlapped
OSError: [WinError 10050] A socket operation encountered a dead network

System information:

• Python 3.11.10 (main, Feb 17 2025, 07:07:12) [MSC v.1942 32 bit (Intel)] on win32
• Microsoft Windows 11 64-bit 23H2 22631.4890

The greater context is that it breaks PyGObject and BleachBit.

CPython versions tested on:

3.11

Operating systems tested on:

Windows

Empieza con asyncio/init.py y asyncio/windows_events.py; después reproduce la importación en el modo seguro mínimo de Windows 11 para examinar el fallo de _overlapped. El fix debe permitir que import asyncio se complete cuando la compatibilidad con sockets no esté disponible, preservando al mismo tiempo el comportamiento normal de asyncio en Windows.
