Describe
老版本静态图AMP接口只支持FP16。为了兼容老版本，Paddle 2.5版本计划新增一个同名函数
paddle.static.amp.decorate，通过dtype、level配置不同数据类型、不同级别AMP训练。（相关功能已经在#52694中实现，PR中暂时新增了一个amp_decorate接口。）本PR参考文章为什么 Python 没有函数重载？如何用装饰器实现函数重载？，实现了专为
decorate设计的overload功能，从而支持框架中同时存在2个paddle.static.amp.decorate函数，且能自动通过参数选择正确的版本。flake会自动检查python是否定义了同名函数，故将该文件加入了ignore列表中。
