Update libcxx to 02 June 2023 185b81e034ba60081023b6e59504dfffb560f3e3 (llvmorg-16.0.5)

:warning:  Для всех проектов и мимо проходящим коллегам :warning:

Если по каким-то причинам ваши тесты подломались, пожалуйста, переканонизируйте их сами. По статистике там просто поменялся порядок в канонизации.
Если изменения действительно серьезные -- приходите в [DEVTOOLSSUPPORT](https://st.yandex-team.ru/createTicket?queue=DEVTOOLSSUPPORT) / пишите в телеграм / призывайте в тикеты, будем разбираться.

```
