While the windows CRTs (the modern UCRT, and the legacy msvcrt.dll that mingw still often defaults to) do provide stat functions, they're a bit lacking - they only provide second precision on the modification time, lack support for symlinks and a few other details.

Instead reimplement them using a couple windows native functions, getting exactly the info we need. (Technically, the implementation within the CRT calls these functions anyway.)

If we only need a few fields, we could also do with fewer calls, as a later optimization.
