[DoctrineBundle] deprecate EventSubscriberInterface

[alli83]

Doctrine subscribers are flawed because they force eager loading by design so the goal since symfony/symfony#49918 and #1650 is to push projects to use attributes to register their listeners through autoconfiguration. In order to achieve this goal, this PR propose to deprecate the EventSubscriberInterface available in doctrine/doctrine-bundle.

Hi,

I have the following use case that I needs in one subscriber to listen to multiple events at once

class MySubscriber implements EventSubscriberInterface
{
    ...

    public function getSubscribedEvents(): array
    {
        return array(
            Events::postUpdate,
            Events::preUpdate,
            Events::postLoad,
            Events::onFlush,
            Events::preFlush,
            Events::postFlush,
        );
    }
}

Do I need to declare 6 attributes #[AsDoctrineListener(event: Events::postPersist)], #[AsDoctrineListener(event: Events::preFlush)] ... to remove the deprecation and resolve my use case?

suggestion: what about create attribute #[AsDoctrineSubscriber]?

Regards

Yes, define 6 attributes, I don't see the issue.

No issue just a question (and suggestion for lazy ones like me 😄)
