[php-src] Issue #7772: Destruction segmentation fault for deeply nested objects

I don't see a good way to fix this. In case we switch to a user-growable stack, we will also have to support arrays and dynamic properties that might double memory consumption. Freeing object before its properties also makes troubles for typed properties. I prefer to keep the current behavior.
