segment_pool_grad_kernel.h建议放在开头

这里不需要转成proto::VarType了，直接用DataType类型做判断就行

||
| namespace phi { | ||
|
|
||
| using Tensor = DenseTensor; |
| length.Resize(phi::make_ddim({1})); | ||
| IndexT* length_data = dev_ctx.template HostAlloc<IndexT>(&length); | ||
|
|

| // IndexT* length_data = length.data<IndexT>(); |
| const std::string& pooltype, | ||
| DenseTensor* out, | ||
| DenseTensor* summed_ids) { | ||
| auto index_type = paddle::framework::TransToProtoVarType(segment_ids.dtype()); |

这里前向ArgumentMapping感觉可以不写，用默认的应该也能work
