Engine calls to private destructors cause errors

Description

https://3v4l.org/bKijA

While private magic method declarations result in a visibility warning, they still work when invoked by the engine as in the cases of __debugInfo (and __sleep since 8.1)

Private destructors however cause errors whenever an instance goes out of scope. The engine should always be able to invoke a destructor when destroying an instance.

首先，使用链接的 3v4l 示例重现该失败，并检查 PHP 引擎的对象销毁路径。该 issue 没有指定源文件或回归测试，因此请跟踪实例离开作用域时析构函数可见性的处理方式。当 private 析构函数在引擎驱动的销毁过程中不再导致错误时，即表示完成。
