feature: adding support for AsyncInferenceConfig in endpoint config

The EndpointConfig constructor could be extended to support passing in AsyncInferenceConfig
which includes configuration as shown here in the doc [API_AsyncInferenceConfig](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_AsyncInferenceConfig.html)
In this way would be possible to create an EndpountConfig supporting [Asynchronous Inference](https://docs.aws.amazon.com/sagemaker/latest/dg/async-inference.html).

从 EndpointConfig 构造函数开始，将其当前的配置输入与 issue 中链接的 AWS API_AsyncInferenceConfig 文档进行比较。跟踪端点配置的表示方式，并验证生成的配置支持 AWS 所描述的异步推理设置；完成的标准是用户可以使用 AsyncInferenceConfig 创建 EndpointConfig。
