    libstdc++: Fix use of inaccessible private member in split_view (PR93936)

    We are calling _OuterIter::__current from _InnerIter::operator==, but the
former
    is private within this non-member friend.  Fix this by calling
    _OuterIter::operator== instead, which does the right thing here.

    libstdc++-v3/ChangeLog:

        PR libstdc++/93936
        * include/std/ranges (split_view::_InnerIter::operator==): Compare
        the operands' _M_i rather than their _M_i.current().
        * testsuite/std/ranges/adaptors/split.cc: Augment test.
