[libcxx-commits] [libcxx] [libc++] Fix incorrect size check when growing std::string (PR #232737)

My understanding is that the new tests don't cover `__grow_by_and_replace`. On 64-bit platforms, it should be possible to hit the subject issue with `__grow_by_and_replace` cases using a custom allocator that uses a 32-bit `size_type`.
