project6-dev f4e2264a83 ref(EX): import upstream ILU kernels + xllm MoE CUDA sources into ex_engine
Copied from upstream_ref (NOT rewritten — exact upstream code):

ixformer C++ API (the authoritative header):
  include/ixformer.h — ixformer::infer namespace: topk_softmax,
    moe_compute_token_index_api, moe_w16a16_group_gemm, moe_expand_input,
    moe_output_reduce_sum, silu_and_mul, rms_norm, xllm_paged_attention, etc.
  include/ilu_ops_api.h — xllm::kernel::ilu namespace: moe_active_topk,
    moe_gen_idx, moe_expand_input, group_gemm, moe_combine_result,
    batch_prefill, batch_decode, rms_norm, matmul, act_and_mul, etc.

ILU kernel wrappers (call ixformer::infer directly):
  csrc/ilu_kernel_fused_moe.cpp — topk routing + gen_idx + expand + combine
  csrc/ilu_kernel_group_gemm.cpp — batched expert GEMM
  csrc/ilu_kernel_{activation,norm,rope,matmul,attention}.cpp

ILU layer implementations (full pipeline):
  csrc/ilu_layer_fused_moe.{cpp,h} — 797 lines, the complete MoE pipeline
    that competitor 168 ran as corex_moe.py
  csrc/ilu_layer_attention.{cpp,h} — prefill/decode attention dispatch

CUDA MoE kernels (from xllm + ds_vllm):
  csrc/moe/moe_topk_softmax_kernels.cuh — CUB BlockReduce + warp topk
  csrc/moe/moe_topk_sigmoid_kernels.cuh — sigmoid scoring variant
  csrc/moe/moe_topk.cuh + moe_fused_topk.cu — entry points
  csrc/moe/moeTopKFuncs.cuh — TRT-LLM derived vllm-compatible topk
  csrc/moe/moe_ops.h + moe_align_sum_kernels.cu — alignment kernels

Common layer headers:
  csrc/common_fused_moe{,_base}.h + common_moe_fused_topk.{cpp,h}
