add preview 3d node

[jtydhr88]

Even we discussed in #5564 that should move this preview 3d into FE, however after investigated, I could not figure out how to do that, the main reason is when execute workflow, comfyUI will validate note mapping here

ComfyUI/execution.py

Line 775 in 6d1a3f7

class_ = nodes.NODE_CLASS_MAPPINGS.get(class_type, None)

but the pure FE node doesn't have such Python Class, I believe we still need one BE node here.
Here is a demo video

FE PR is Comfy-Org/ComfyUI_frontend#1918

Note: currently model_file is a string path. We probably want to define a 3D data type in ComfyUI? @jtydhr88 Can you help define a universal 3D data type that is easy to handle?

Can you rebase to the head of master? Missing imports are fixed in 0b25f47
