Implement tool calling for ChatBedrock

[eugeneduvenage]

Currently ChatBedrock cannot easily be used for tool calling when using langchain agents as it does not implement the bind_tools method. An example would be this langchain example using Anthropic: https://python.langchain.com/docs/use_cases/tool_use/agents/ and the create_tool_calling_agent function.

Are there any plans to support this common use case, at least when using Bedrock Anthropic models?
It might also be nice to add the BedrockChat to the langchain integrations page here: https://python.langchain.com/docs/integrations/chat/ so that the supported features can easily be understood.

This is the PR. Right now, it is only supporting Anthropic models.

@eugeneduvenage
Tool support has been added both in ChatBedrockConverse and ChatBedrock classes, can you try again and let us know if you come across any issue.

Thanks in advance
