Compares the underlying iterators (or the underlying iterator and the default sentinel (2)).

Let current_ and end_ be the underlying data members.

Equivalent to:

1) return x.current_ == y.current_;.
2) return x.current_ == x.end_;.
3) return x.current_ < y.current_;.
4) return y < x;.
5) return !(y < x);.
6) return !(x < y);.
7) return x.current_ <=> y.current_;.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::chunk_view::iterator<Const> is an associated class of the arguments.

The != operator is synthesized from operator==.
