Compares the underlying iterators.

Let `current_` and `last_ele_` be the underlying iterators to the begin and end of the sliding window, respectively.

1) Equivalent to:

- return x.last_ele_ == y.last_ele_;, if `last_ele_` is present. Otherwise,
- return x.current_ == y.current_;.

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

The `!=` operator is synthesized from `operator==`.
