Add support for trace sets

Keep in mind there are some shaders that support trace sets. I'll try to keep track of them here as best I can.

I was just thinking about this and how we can keep the track of the nodes that needs Trace Sets implemented. It's a good idea to have this issues open with the list of all the nodes that supports Trace Sets. 👍
