Currently, `size_t` and `__libcpp_is_constant_evaluated` are obtained by transitive inclusion in `<__algorithm/find.h>` when `<cwchar>` is not included. This broke module build when `_LIBCPP_HAS_WIDE_CHARACTERS` is `1` and caused CI failure. We should explicitly include the corresponding internal headers.
