Register Ndr Nodes for shapes, lights, filters, drivers and the options node

The Ndr Discovery and Parser plugins should register all the other node types available in arnold.

**Describe the solution you'd like**
All we need to do is to change the Node Entry iterator and manually handle the options node in `ndr/utils.h`.

Start in ndr/utils.h and inspect the Node Entry iterator used by the Ndr Discovery and Parser plugins. Trace how existing node types are registered, then verify that shapes, lights, filters, drivers, and the options node are all registered. Done means every other Arnold node type is discoverable through these plugins.
