The internal iterator for std::ranges::repeat_view has been extracted into a separate class, _Repeat_iterator, in bits/ranges_util.h. This change allows the iterator to be used in other parts of libstdc++ without pulling in the entire std/ranges header. It also enables new overloads for container functions and improves how iterators are constructed and specialized, especially concerning sentinels and difference types.
