Construct the `second` member of a `pair`, forwarding in order the elements in the specified `argsPack` to the corresponding constructor of (template parameter) `TYPE`. The length of the `argsPack` is equal to the length of the specified (template parameter pack) `I...` and passed to the constructor via the `Pair_IndexSequence` object.
