As suggested in #88564. This adds a try_clone() to OwnedFd by
refactoring the code out of the existing File/Socket code.

Long-term, I wonder if we can eliminate this internal interface in favor of try_clone. But that's not an issue for this PR.

The CI now passes; @joshtriplett I think this just needs an r+.

As a follow-up, I think we should investigate whether we can drop the special-case handling of systems without F_DUPFD_CLOEXEC. (In particular, I'm wondering if the platform could instead automatically handle F_DUPFD_CLOEXEC and translate it to F_DUPFD, or alternatively if we should export the flag from libc as an alias for compatibility.)

Use the correct cvt for converting socket errors on Windows.
83aebf8 
`WSADuplicateSocketW` returns 0 on success, which differs from
handle-oriented functions which return 0 on error. Use `sys::net::cvt`
to handle its return value, which handles the socket convention of
returning 0 on success, rather than `sys::cvt`, which handles the
handle-oriented convention of returning 0 on failure.

The CI failure turned out to be that the code was calling cvt, and when it was moved to a different file, it silently started calling a different cvt. On Windows, one cvt treats 0 as indicating a failure, while the other cvt treats 0 as indicating success.

@sunfishcode Good catch. That seems like a source of potential future bugs. Would you consider a separate PR to rename the socket-like one to cvt_socket or similar, to make the behavior difference more obvious?

This puts the actua clone logic under control of `feature = "close"`, as
