Materials: Convert to classes.

Description

Converts the remaining materials to class syntax.

It was necessary to migrate the "old" NodeMaterial. However, I'm not going to convert the complete jsm/nodes directory since it will be replaced at some point with the new node material in jsm/renderers/nodes.

Thanks!

I believe that we will maintain the properties of the materials used in the WebGPU version when this migration happens?

Do you mind explaining in more detail what you mean?

StandardNodeMaterial is a minimalist node-based material while MeshStandardNodeMaterial is a hybrid version, supports default material values as well nodes. MeshStandardMaterial of WebGPU uses differents properties names like .colorNode and .alphaNode. For this reason, I think that we no need continue with this old API syntax (StandardNodeMaterial) or need?

Ah okay. Yes @mrdoob mentioned that existing material properties should still work. I also think this is best since ideally it will make the transition from WebGL to WebGPU easier.
