[php-src] Issue #9702: A override for a trait methods.

Issue: https://github.com/php/php-src/issues/9702 Author: allanmcarvalho ### Description Sometimes we created a Trait that is used in a lot of class, or only use a trait of a dependency package. I believe that this is so common today at PHP modern projects. But I see a big opportunity of improvement on this. Today, when we want to implement some code lines before or after a parent class method is very easy, we just to do: ```php protected function parentMethod(mixed $fooAttribute): mixed { // do something here $result = parent::parentMethod($fooAttribute); // or do something here return $result; } ``` I believe that a similar behavior will be very nice on traits, but I don't found a correspondent code to do this with it. Maybe the right suggestion to do this is: ```php protected function traitMethod(mixed $fooAttribute): mixed { // do something here $result = trait::traitMethod($fooAttribute); // or do something here return $result; } ``` Make sense or it's a bad idea?
