RBAC classification resources should not store default-xxx attribute values in the DMR model

The RBAC classification resource are storing the values of the relevant default-requires-xxx attributes in the DMR model even though those are runtime-only attributes. The DMR value is unused in read-resource/read-attribute because the read handlers for the attribute don't read from DMR.

Unless WFCORE-4185 is fixed these will get propogated to slave HCs when they connect though.

Cleaning this up helps resolve WFCORE-4183 by removing irrelevant data that confuses domain mode transformer tests.
