accesscontrol swagger: Add global field to RoleDTO type (#79351)

* `accesscontrol` swagger: Add `global` field to `RoleDTO` type
The field is currently added in the MarshalJSON function so it isn't reflected in the spec
This PR sets the "static" version of the RoleDTO, that has the global field, as the swagger model

* Revert the marshalling logic
