Compares the underlying iterators/sentinels.

Let current_ be the underlying iterator, and end_ be the underlying sentinel.

1) Equivalent to return x.current_ == x.end_;.
2) Equivalent to return x.current_ == y.current_;.
3) Equivalent to return x.current_ < y.current_;.
4) Equivalent to return y < x;
5) Equivalent to return !(y < x);
6) Equivalent to return !(x < y);
7) Equivalent to 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::stride_view::iterator<Const> is an associated class of the arguments.

The != operator is synthesized from operator==.
