    libstdc++: Do not define __cpp_lib_ranges_iota in <ranges>
    
    In r14-7153-gadbc46942aee75 we removed a duplicate definition of
    __glibcxx_want_range_iota from <ranges>, but __cpp_lib_ranges_iota
    should be defined in <ranges> at all.
    
    libstdc++-v3/ChangeLog:
    
            * include/std/ranges (__glibcxx_want_ranges_iota): Do not
            define.
