Describe

Sparse backward API支持通过Yaml配置完成接口代码的自动生成。Sparse 前向API可参考#PR40060

以sparse_conv3d_grad为例，其yaml配置格式如下：

- sparse_bw_api : conv3d_grad forward : conv3d (Tensor x, Tensor kernel, int[] paddings, int[] dilations, int[] strides, int groups) -> Tensor(out@SparseCooTensor), Tensor(rulebook@DenseTensor) args : (Tensor x, Tensor kernel, Tensor rulebook, Tensor out_grad, int[] paddings, int[] dilations, int[] strides, int groups) output : Tensor(x_grad@DenseTensor), Tensor(kernel_grad@DenseTensor) kernel : func : sparse_conv_grad 

配置规则与普通反向API基本相同，区别在于：

1. 无需配置infer_meta项
2. output项中的变量名需使用 "@xxx" 的后缀标记返回Tensor的具体数据类型
