2eb2ff2a02 [libc++] Merge _LIBCPP_HAS_NO_RANGES into _LIBCPP_HAS_NO_CONCEPTS. NFC.
The macro that opts out of `std::ranges::` functionality is called
`_LIBCPP_HAS_NO_INCOMPLETE_RANGES`, and is unrelated to this macro
which is specifically about _compiler_ support for the _syntax_.

The only non-mechanical diff here is in `<__config>`.

0902eb30ad [libc++] Fix common_iterator for output_iterators
We were missing a constraint in common_iterator's iterator_traits and
we were eagerly instantiating iter_value_t even when invalid.

Thanks to Casey Carter for finding this bug.
