Tool/function calling on Mistral and HuggingFace

[hajajmaor]

Feature request

On the docs stated that only some models supports tool calling. Please add support to more models/providers like Mistral or HF

Tool calling is currently supported by:

[ChatAnthropic](https://langchaindart.dev/#/modules/model_io/models/chat_models/integrations/anthropic)
[ChatFirebaseVertexAI](https://langchaindart.dev/#/modules/model_io/models/chat_models/integrations/firebase_vertex_ai)
[ChatGoogleGenerativeAI](https://langchaindart.dev/#/modules/model_io/models/chat_models/integrations/googleai)
[ChatOllama](https://langchaindart.dev/#/modules/model_io/models/chat_models/integrations/ollama)
[ChatOpenAI](https://langchaindart.dev/#/modules/model_io/models/chat_models/integrations/openai)

Motivation

Building an app with Langchain usecases, i want to use providers that have low to no cost at all.

Your contribution

I tried to update the code on the HF pr, to add the chat model, no success there. I would love to help more to support this great set of packages to use.
