We originally put implementation-detail function objects into individual namespaces for `std::ranges` without a good reason for doing so. This practice was continued, presumably because there was prior art. Since there's no reason to keep these namespaces, this commit removes them, which will slightly impact binary size. This commit does not apply to CPOs, some of which need additional work.
