[php-src] Issue #14342: Exceptions are still not clonable even if Exception::__clone() is no longer final

Issue: https://github.com/php/php-src/issues/14342 Author: SigmaFlame ### Description Hello, While reading the PHP documentation, I have read that the method Exception::__clone() is no longer final since PHP 8.1. But, trying to extend the class Exception and making its own « public function __clone() » does not work and still produce an error. « Trying to clone an uncloneable object of class ExtendedException » What is the purpose of removing the final attribute of this method if we still can't clone an exception? I would like to make the exception clonable in order to update the file and line where the exception has occurred. Thanks you in advance. ### PHP Version 8.3.7 ### Operating System _No response_
