原生op定义中，axis 可以是 int也可以是list（vector），这里看起来只考虑了list 的情况？

原生op通过在python源代码中转成list支持int，convert时候只能拿到vector

这个是一个必要属性，组网的时候如果没有这个属性会报错，可以不加这个回退条件

Description
Pcard-71501
借助Loop实现了flip算子到TRT的映射，并添加相应单测。
整体的逻辑参考paddle2onnx中的flip -> split + concat的思路，Loop中的IIteratorLayer可以通过指定reverse参数实现split + reverse的效果，ILoopOutputLayer可以实现concat的效果。
