移除 forward 中对 experts.use_overlapped/_shared_experts 的状态改写，避免 torch.compile 启动期 shared/non-shared 路径不一致
FusedMoE.forward_impl 仅在 shared_output 为空时计算 shared experts，防止透传值被本地重算覆盖

  新增环境变量 VLLM_USE_LIGHTOP_MOE_SUM_MUL_ADD 用于控制
  fused sum+mul+add 开关。
  在 DeepseekV2MoE 中增加 fused 路径，预计算 shared_output，并下传 iqis 与 routed_scaling_factor。
  扩展 FusedMoE/SharedFusedMoE 及相关 custom op 接口，统一透传 i_q/i_s/shared_output/routed_scaling_factor。
  同步适配 Triton、Marlin W16A16、SlimQuant W4A8、CompressedTensors W8A8 等实现，支持在内核侧完成 sum+mul+add。
