Constructs a new iterator adaptor.

1) Default constructor. The underlying iterator is value-initialized. Operations on the resulting iterator have defined behavior if and only if the corresponding operations on a value-initialized Iter also have defined behavior.
2) The underlying iterator is initialized with x(until C++20)std::move(x)(since C++20).
3) The underlying iterator is initialized with that of other. The behavior is undefined if U is not convertible to Iter(until C++20)This overload participates in overload resolution only if U is not the same type as Iter and std::convertible_to<const U&, Iter> is modeled(since C++20).
