This fix addresses the undefined symbol error for torch::executor::native::choose_qparams_tensor_out when building on native Windows. The root cause is a mismatch between the return types in the function declaration (std::tuple<Tensor &, Tensor &>) and the function definition (std::tuple<Tensor, Tensor>). Additionally, the function definition cannot see the function declaration, so the compiler cannot catch the issue. While the Linux linker seems to handle the return type mismatch, the Windows linker reports an undefined symbol. This fix updates the return type in the function definition to match the function declaration. If possible, it would be beneficial to include the header of the function declaration so that the issue can be caught at compile time.
