Summary: This diff expands the templatization of FBGEMM's cutlass groupwise GEMM to include options to limit the swizzling of loaded tiles and implicitly transpose tiles. We introduce a bit of additional tuning that shows this allows us to get decent performance in both compute and memory bound domains. In a followup diff, we will dramatically expand these heuristics for better performance. Differential Revision: D78537461
