`mp_transform<F, L1<T1...>, L2<T2...>, ..., Ln<Tn...>>` applies `F` to each successive tuple of elements and returns `L1<F<T1, T2, ..., Tn>...>`.
All lists in `L...` must be of the same size. Otherwise, the result is a substitution failure.
Has limited support of value lists as `L...` under {cpp}17 (for one to three lists.)
In that case, elements are wrapped with `mp_value` before being passed to `F`, and
are unwrapped afterwards. The result is `L1<F<mp_value<T1>, mp_value<T2>, ...>::value...>`.
