Constructs a tagged object.
1) tagged<Base, Tags…> inherits the constructors of Base.
2-4) tagged has defaulted default, copy, and move constructors that invoke the corresponding constructor of Base.
5) Converting move constructor from Base. Initializes the Base subobject with std::move(that).
6) Converting copy constructor from Base. Initializes the Base subobject with that.
7) Converting move constructor from a different tagged specialization with matching tags. Initializes the Base subobject with static_cast<Other&&>(that).
8) Converting copy constructor from a different tagged specialization with matching tags. Initializes the Base subobject with static_cast<const Other&>(that).
