Compares the underlying iterators: `inner_`.

1) Equivalent to return x.inner_ == y.inner_;.
2) Equivalent to return x.inner_ < y.inner_;.
3) Equivalent to return x.inner_ > y.inner_;.
4) Equivalent to return x.inner_ <= y.inner_;.
5) Equivalent to return x.inner_ >= y.inner_;.
6) Equivalent to return x.inner_ <=> y.inner_;.

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

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