23c92de8 - [libc++][test] Add backported `destroy({_at,_n})` for tests (#199185)

[libc++][test] Add backported `destroy({_at,_n})` for tests (#199185) It would be convenient to use `destroy_at`, `destroy`, and `destroy_n` in tests for pre-C++17 uninitialized memory algorithms. So this PR add backported versions of them for tests.
