What does this PR do / why do we need it:
背景：解决高版本下默认针对没有注册autograd相关key但进行反向的api的告警
方案：通过提供支持添加dispatch字段注册到autogradprivateuse1上，避免出现告警：
例如：

  - func: npu_moe_token_unpermute_with_routing_map(Tensor permuted_tokens, Tensor sorted_indices, int[] restore_shape, *, Tensor? probs=None, Tensor? routing_map=None, bool drop_and_pad=False) -> Tensor
    op_api: [v2.1, newest]
    dispatch:
      AutogradPrivateUse1: npu_moe_token_unpermute_with_routing_map

具体样例：
添加dispatch前存在告警，添加后无

[W919 12:36:08.793215810 compiler_depend.ts:67] Warning: npu::npu_moe_token_unpermute_with_routing_map: an autograd kernel was not registered to the Autograd key(s) but we are trying to backprop through it. This may lead to silently incorrect behavior. This behavior is deprecated and will be removed in a future version of PyTorch. If your operator is differentiable, please ensure you have registered an autograd kernel to the correct Autograd key (e.g. DispatchKey::Autograd, DispatchKey::CompositeImplicitAutograd). If your operator is not differentiable, or to squash this warning and use the previous behavior, please register torch::CppFunction::makeFallthrough() to DispatchKey::Autograd. (function operator())
