Requires an extra NtQueryInformationFile call when FILE_ATTRIBUTE_REPARSE_POINT is set to determine if it's actually a symlink or some other kind of reparse point (https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-point-tags). This is something that `File.Metadata.kind` was already doing, so the same technique is used in `stat`. Also, replace the std.os.windows.DeviceIoControl call in `metadata` with NtQueryInformationFile (NtQueryInformationFile is what gets called during kernel32.GetFileInformationByHandleEx with FileAttributeTagInfo, verified using NtTrace).
