[libc++][ranges] Mark completed Ranges papers and issues as done, bump version macro
All C++20 Ranges papers and LWG issues are done, with the exception of
https://wg21.link/P2210R2 ("Superior String Splitting"), and marked as
such.
All of these were already implemented prior to this patch except bumping
the feature test macro `__cpp_lib_ranges` as required by
https://wg21.link/P2325R3 ("Views should not be required to be default
constructible"). Note that, even though P2325R3 was voted into C++23, it
was voted with a recommendation for vendors to retroactively apply the
change to C++20 (see https://github.com/cplusplus/papers/issues/1007).
