FEATURE: Blocking is optional when deleting a user from the review queue. (#13375)

Subclasses must call #delete_user_actions inside build_actions to support user deletion. The method adds a delete user bundle, which has a delete and a delete + block option. Every subclass is responsible for implementing these actions.
