Description
为 expand_as 和 expand_as_grad 算子增加切分推导规则。
为动态图自动并行适配expand_as kernel(vector类型，之前有了 intarray)的 local_shape 逻辑
但是反向复用了这个函数，对于 expand_grad 也是，给 kernel 传入的 shape，并不是 out_grad 对应的 shape，已经变成 x_grad 的 shape，这里使用 [Auto Parallel] Try to refine dist_api_gen #73114 进行修复
适配 optional 类型的输入y
已有切分推导规则，直接在 ops.yaml 中进行注册
