For MoE inference, mixed type group-gemm is helpful. But now cutlass seems only support mixed type matmul, and group-gemm of non-mixed type.
Describe the solution you'd like
group-gemm of fp16_int4, fp16_int8, e4m3_int4

Research direction
The request names mixed-type group-gemm support for fp16_int4, fp16_int8, and e4m3_int4, but provides no files, tests, or entry points. Start by locating the existing mixed-type matmul and non-mixed group-gemm implementations, then determine the integration and validation points. Done means the requested Hopper combinations are supported and covered by appropriate tests.
