Ensure ConfigEntities providing a list controller use admin_permission

Updated: Comment #N

Problem/Motivation

#2105557: Add an admin_permission to EntityType annotations to provide simple default access handling added the very useful admin_permission annotation property. This removes the need for an access controller in most cases, and still simplifies the ones that exist.

However, it is not fully used yet, which is confusing for contrib module authors, especially since the access controller is optional. It will happily deny you access, even as uid 1.

Proposed resolution

Ensure that all config entities with list controllers have a permission defined.
