perf(fused-moe): 预打包 Marlin W16A16 MoE 权重，降低 warmup 显存峰值

See merge request dcutoolkit/deeplearing/vllm!358

在 post-load hook 中对 w13/w2 做 per-expert Marlin pack，并替换为 packed 参数
Marlin fast path 仅接受 packed 权重；未预打包则 fail fast，避免运行时 packing 峰值/不确定性
更新 Marlin wrapper 的入参与 shape 推导（从 packed layout 计算 K/N）

区分pcie和hglink custom allreduce的使用
vllm：export VLLM_CUSTOM_CACHE=1
dtk：export HIP_KERNEL_EVENT_SYSTENFENCE=1

perf(fused-moe): 接入 W16A16 Marlin MoE 并缓存 pack 权重

See merge request dcutoolkit/deeplearing/vllm!347

 - fused_experts_impl 增加 VLLM_USE_MARLIN_W16A16_MOE fast path：首次对 w1/w2 做 Marlin pack 后缓存，避免重复 reorder；并将原始
    权重 offload 到 CPU，降低 GPU 双份驻留
  - envs 补齐环境变量 VLLM_USE_LIGHTOP_MOE_SUM_MUL_ADD
  - 更新 fuse_moe_w16a16_marlin.py 的报错提示为 VLLM_USE_LIGHTOP=1
