Andrew Kelley d3f87f8ac0 std.fs.rename: fix Windows implementation
The semantics of this function are that it moves both files and
directories. Previously we had this `is_dir` boolean field of
`std.os.windows.OpenFile` which required the API user to choose: are we
opening a file or directory? And the other kind would either cause
error.IsDir or error.NotDir. But that is not a limitation of the Windows
file system API; it was self-imposed.

On Windows, rename is implemented internally with `NtCreateFile` so we
need to allow it to open either files or directories. This is now done
by `std.os.windows.OpenFile` accepting enum{file_only,dir_only,any}
instead of a boolean.
