[CORE][GEN][ZH] Add missing virtual destructors for virtual classes

[Caball009]

Some virtual classes have no virtual destructor, which leads to compiler warnings when an object of such a class is manually deleted:
delete called on non-final 'Class' that has virtual functions but non-virtual destructor [-Wdelete-non-abstract-non-virtual-dtor]
destructor called on non-final 'Class' that has virtual functions but non-virtual destructor [-Wdelete-non-abstract-non-virtual-dtor]

If it helps with the review process, I could provide a list with class name + filename + line number where the delete happens / the compiler warnings originate. I can also provide that in the form of an url.

I noticed more classes with virtual functions but without virtual destructor. I assume no instances of such classes are manually deleted, so the compiler may not issue a warning for it.

did you make sure that a virtual destructor was needed and that it wouldn't just be better to make the base destructor non-virtual?
