Proposal: Using LuisaCompute for Multi-Backend Support

[MuGdxy]

I would like to propose using LuisaCompute as a solution to achieve further multi-backend support. By leveraging LuisaCompute, we can simplify the process of covering multiple backends such as CUDA, DirectX, and Metal, enabling broader compatibility and flexibility in our development efforts.

This approach could potentially save significant development time and improve maintainability while allowing users to choose the backend that best suits their needs.

Looking forward to your feedback and ideas!
