deps: upgrade to libuv 1.40.0

Notable changes:

- The UV_UDP_MMSG_FREE flag has been added.
- UV__EPROTO has been remapped from 4046 to -4046 for
  consistency with other error codes.
- On Windows, UTF-16 surrogate pairs are no longer
  replaced with the Unicode replacement character.
- uv_timer_get_due_in() has been added.
