Implemented code change tracking for selfdestruct operations by adding OnCodeChange hooks in the SelfDestruct and SelfDestruct6780 methods of the hookedStateDB structure.

Motivation:
Now, we can track OnCodeChange when the contract is deployed. It would be nice also to be able to track changes (code, codeHash) when the contract is destroyed.

Let me know if this makes sense or if I need to improve/fix anything

I think the change makes sense. But let's do it together with #30441 as part of a single release.

@maoueh wondering how you are handling this right now. Listening to OnEnter and manually clear the code?

Correct, we work with the OnEnter and check if is a SELFDestruct to deal with this.

This change invokes the OnCodeChange hook when selfdestruct operation is performed, and a contract is removed. This is an event which can be consumed by tracers.
