Description

完善IR yaml 生成算op 自动代码生成逻辑，主要内容包括：

• 添加基于 legacy_ops.yaml 自动生成算子定义；
• 定义 GetOpInfoInterface，用于获取 yaml 中定义的算子输入、输出、属性信息；
  算子定义形式如下：

class SumOp : public ir::Op<SumOp> {
 public:
  using Op::Op;
  static const char *name() { return "pd.sum"; }
  static const char *attributes_name[3];
  static constexpr uint32_t attributes_num = 3;
  static std::tuple<std::vector<OpInputInfo>, std::vector<OpAttributeInfo>, std::vector<OpOutputInfo>> GetOpInfo();
  static void verify(const std::vector<ir::OpResult> &inputs, const std::vector<ir::Type> &outputs, const ir::AttributeMap &attributes);
  ir::OpOperand x() { return operation()->GetOperandByIndex(0); }
  ir::OpResult out() { return operation()->GetResultByIndex(0); }
};
