Unify the function calling for all LLM in JSON Schema

[Oceania2018]

Currently, among the large language models on the market, only ChatGPT provides the function calling function. As a result, if the system relies on the function calling function, the model cannot be switched. The purpose of this feature is to implement an abstraction layer for function calls at the application layer to enable compatible switching between various models.
