MultiGPU node native and built-in support

### Feature Idea

Hello! There is a great node for ComfyUI called MultiGPU https://github.com/pollockjj/ComfyUI-MultiGPU. It allows to distribute memory between VRAM and RAM very effectively. With my RTX 3080 10GB and 64GB VRAM I can generate even with heavy models like Flux 2 fp8. But the problem is that after each big ComfyUI update it doesn't work well and the developer doesn't have time to update it quickly. So it will be perfect if this node become native and basic for ComfyUI and be supported constantly. This would give most users an excellent opportunity to generate on various advanced models while having mid-range systems.
Thank you for your attention!
