We should have a callback handler that supports sending tracing data to LangSmith

In the process of implementing LangSmith’s handler, I encountered some issues.

For Python, enabling LangSmith in LangChain is a seamless action that only requires an environment variable. However, for langchaingo, it’s not as easy. Currently, I haven’t found a place to globally control the invocation of various models. Developers can bypass llms and directly call a specific model’s methods, from New to Call. This way, there is no place to inject this handler.
