LibOverride: Make nodetree of material overrideable again.

This reverts rB6899dbef77cd and makes the pointer explicitely
processable by override & diffing code.

Previous changes & fixes have fixed the 'driver-workaround' case afaict.

Note that this only enables proper generic handling of overrides and
their ID pointers, no node property is actually overridable currently.
