Expose shading node shading compatibility to the RNA 

This way it is possible to probe shading compatibility of a given node from
python, making things like versioning code much easier to perform.

it's only valid for shading nodes, for other nodes the property also exists
but reads as an empty enum.

To access this compatibilities:

  node.shading_compatibility
