mingw_rename: support ReFS on Windows 2022 (#5515)

Git on Windows 2022 fails to write config files on ReFS with the error
message "Function not implemented". The reason is that
`ERROR_NOT_SUPPORTED` is reported (not `ERROR_INVALID_PARAMETER`, as
expected). Let's handle both errors the same: by falling back to the
best-effort option, namely to rename without POSIX semantics.

This fixes #5427
