问题/功能描述

本次PR为ArgMaxWithValue和ArgMinWithValue算子新增了可选的indice_dtype属性，以解决算子输出索引数据类型固定为DT_INT32的问题。该增强使得算子能够灵活输出DT_INT64类型的索引，从而更好地兼容需要更大索引范围的场景（如PyTorch框架对接），提升了算子的灵活性和跨框架兼容性。

修改方案描述

在ArgMaxWithValue和ArgMinWithValue两个算子的原型定义中，分别增加了一个名为indice_dtype、类型为Type的属性，并将其默认值设置为DT_INT32。该方案允许用户在调用算子时显式指定输出索引的数据类型（DT_INT32或DT_INT64），而无需修改算子内核或依赖外部转换，简化了使用流程并增强了接口的易用性。
