Not enabling native lazy objects on PHP 8.4+ is deprecated since Doctrine ORM v3.5

This PR adds the config `enable_native_lazy_objects: true` to fix the deprecation on PHP 8.4+ and removes the config `enable_lazy_ghost_objects` as it's no longer needed.

With Doctrine ORM v3 installed the DoctrineBundle enables the lazy ghosts by default (doctrine/DoctrineBundle#1722) and in Doctrine ORM v3 the lazy ghosts are enabled unconditionally (doctrine/orm#10969).

The config `enable_native_lazy_objects: true` is only enabled on PHP 8.4+
