[libcxx-commits] [libcxx] [libc++] Fix constant initialization of unique_ptr in C++17 and prior (PR #108956)

Would these tests fail if we refactored to run them in a `constexpr` context, or is this *required* to use `constinit`? I'm worried that this is a roundabout way of testing this and that we could lose the coverage in the future via some refactoring.
