std: Set overlap/noinherit flags on windows sockets
This commit modifies the socket creation functions on windows to always specify the `WSA_FLAG_OVERLAPPED` and `WSA_FLAG_NO_HANDLE_INHERIT` flags by default. The overlapped flag enables IOCP APIs on Windows to be used with the socket at no cost, enabling better interoperation with external libraries. The no handle inherit flag mirrors the upcoming change to Unix to set CLOEXEC by default for all handles. Closes #24206
