[php-src] Issue #7943: Nested Attributes values are not static through engine life

Issue: https://github.com/php/php-src/issues/7943 Comment Author: aurimasniekis Yes, I understand you can do stupid things, but my point was more about getArguments which returns values for that attribute, and the constructor of that attribute doesn't really matter what it does. My main point is that if you pass something as an argument to an attribute constructor, in this case, some random object (the random_int was just to prove that object changes), the reflection of that attribute when using getArguments should return the same result at least for the same ReflectionAttribute class instance, or best for that engine lifetime. Because if you try to interact with that object instance, and then call somewhere getArguments again it will be replaced as it's not the same instance.
