[php-src] Issue #14493: Trait methods with `Override` attribute with existing parent methods throw error after #14480 was fixed

Issue: https://github.com/php/php-src/issues/14493 Author: spaze ### Description I have a trait method that looks like this ```php trait Traita { #[Override] public function methodWithDefaultImplementation(): int {} } ``` which is used in a class ```php final class Childa extends Parenta { use Traita; } ``` (all in the repo here https://github.com/spaze/php-override-test) and this has started throwing errors () on the patched PHP 8.3.8 after the fix https://github.com/dstogov/php-src/commit/955d717e242c3433cdf76fa353831aefae530cab for #14480 has been applied: ``` PHP Fatal error: Childa::methodWithDefaultImplementation() has #[\Override] attribute, but no matching parent method exists ``` see https://github.com/spaze/php-override-test/actions/runs/9409995626/job/25920912091 I'm running tests with shivammathur/setup-php and they have patched 8.3.8 with the mentioned patch see https://github.com/shivammathur/setup-php/issues/849#issuecomment-2153420979 When run with unpatched deb.sury.org package, there's no error (but the code from #14480 throws errors as expected without the patch). ### PHP Version 8.3.8 + #14480.patch ### Operating System _No response_
