Replace \Drupal\content_entity_base\Entity\Routing\EntityRevisionRouteAccessChecker

• \Drupal\entity\Access\EntityRevisionRouteAccessChecker provides basically the exact same code already so we could replace it
• There might be still some references to it in other parts of the code

We decided to go another way with this and keep our own classes.
