Blender 3.4: LuxCore shader nodes are exposed in search menus of Blender's other node systems

[sunkper]

Steps to reproduce:

• Go to the editor of one of Blender's own node systems (Geometry Nodes, Shader, Compositor, Texture).
• Add -> Search and type names for LuxCoreRender shader nodes. (Blender is a good one because there's a lot of texture nodes named with Blender.)
• You can actually add those nodes to the nodegraph but they do not work or outright crash Blender when you try to connect it.
