(core) Add getAclResources method for making all tables/columns available when editing ACL rules

Summary:
The goal is that those who can edit ACL rules can create or change rules for
any resource, even if the rules block their own ability to see the resource.

Test Plan: Added a browser test, and a server test for who can call the new method.
