Support Sagemaker as chat_models so it can be used for tool calling efficiently

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

Sagemaker hosted models such as (Llama3.1, Mistral, ) all support tool calling. but the lang chain module sagemaker class, doesn't understand correctly the response from AI for tool calling because langchain->sagemaker is missing bind_tools functionality.
Although I created createAiToolAgent, createReActAgent, both are not helpful. doesn't work. I tested my theory with same llama3.1 model hosted on Ollama and ChatOllama works in tool calling. but sagemaker same model doesn't work .

Motivation

I spend a week in understanding langgrah and tool calling. but then realised Sagemaker hosted models are not working LangChain/Langraph. There should be a effiecient chat model for sagemaker to bind tools and interact with AI correctly.
This request is same as bedrock chatmodel request created here. #2744

Proposal (If applicable)

Please following the same pattern for bedrock chat model, there should be a similar sagemaker model too.
