Socketpair authentication fails while Proxifier is enabled

Bug report

Bug description:

In the fallback socketpair implementation for Windows, socket authentication fails while Proxifier (and likely similar tools) are enabled. The following exception is always raised:
https://github.com/python/cpython/blob/e41ec8e18b078024b02a742272e675ae39778536/Lib/socket.py#L644-L648

Originally spotted in: https://github.com/nicotine-plus/nicotine-plus/issues/3265

Relevant discussion on curl's issue tracker: https://github.com/curl/curl/issues/10144

CPython versions tested on:

3.12

Operating systems tested on:

Windows

從 Lib/socket.py 第 644-648 行的 socketpair 備援驗證程式碼開始，在啟用 Proxifier 的 Windows 上重現此故障。將行為與連結的 curl 討論進行比較；當 socket 驗證在此設定下成功且不會引發所回報的例外時，即表示完成。
