file_time: Notice file updates of files in root directory on Windows (bug #59711).
* liboctave/system/oct-time.cc (file_time::file_time): It's not possible to get
a file handle for the root directory of a drive on Windows. Instead use
GetFileAttributesExW to check if files in any folder (including the root
directory) have been updated.
