[Feature Request]: Add Bedrock multimodal LLM integration

[tituslhy]

Feature Description

AWS Bedrock has a few multimodal LLMs such as Claude Opus. It would be great if this can be added as a multi-modal-llm integration. There is already an anthropic multimodal llm integration.

Reason

So that users who have AWS Bedrock credentials but not credentials in multimodal LLM service providers (like Anthropic) can call multimodal LLMs from AWS Bedrock

Value of Feature

This feature is valuable because more cloud providers are serving multimodal LLMs within their spaces. I'm sure the community will appreciate it!
