fused moe fix (#4534)
Summary: X-link: facebookresearch/FBGEMM#1579 A number of changes on CK header that we need downstream fixes: * local token was added to MoeSortingProblemEx: https://github.com/ROCm/composable_kernel/blob/develop/include/ck_tile/ops/fused_moe/kernel/moe_sorting_problem.hpp#L48 * MeshType_ was added to MoeSortingProblemMp: https://github.com/ROCm/composable_kernel/blob/develop/include/ck_tile/ops/fused_moe/kernel/moe_sorting_problem.hpp#L56 * MOE_SORTING_FMOE_2D_BUF was added which I just turn off for now ``` In file included from buck-out/v2/gen/fbcode/de5ab6968d300cd2/deeplearning/fbgemm/fbgemm_gpu/experimental/gen_ai/src/quantize/ck_extensions/__ck_fused_moe_hipify_gen__/out/fused_moe/instances/fused_moesorting_api.hip:4: In file included from fbcode/deeplearning/fbgemm/fbgemm_gpu/experimental/gen_ai/src/quantize/ck_extensions/fused_moe/fused_moesorting.hpp:8: In file included from third-party/rocm_composable_kernel/include/ck_tile/ops/fused_moe.hpp:9: third-party/rocm_composable_kernel/include/ck_tile/ops/fused_moe/kernel/moe_sorting_kernel.hpp:2100:11: error: no member named 'moe_buf_elem_bytes' in 'ck_tile::MoeSortingMultiPhaseKernel_P2<ck_tile::MoeSortingProblemMp<int, float, int, 1, false, false>>::Kargs' 2100 | k.moe_buf_elem_bytes = h.moe_buf_elem_bytes; | ~ ^ ``` Reviewed By: zjing14 Differential Revision: D78679653
