LlaVa model in transformers
### Feature request

Support to Llava model in transformers? https://github.com/haotian-liu/LLaVA Similar to InstructBlip w/ connector module between image embeddings and LLM's

### Motivation

Llava is performing really well in MLLM related tasks and for folks to try out InstructBlip vs Llava models it makes it easier if it's in hugging face as it's mostly using the same Image Encoder embeddings from (EVA or ViT or CLIP) and foundational models from (T5 or Vicuna or Llama-2). Code maintenance and ease of integration is easy

### Your contribution

I can definitely help with a PR or tag along with folks in hugging face to make it happen
Hi @RajeshRadha Thank you for the feature request.

As @ArthurZucker mentioning to me, the repo. has reached 4K starts and 300 fork, it seems this is quite popular.

Will leave our core maintainers @amyeroberts and @sgugger to see if this qualifies the model to be in `transformers` or we still prefer to have it first on the Hub. <|||||>Given the popularity and performance of the model, I think it'd be a good addition into `transformers` :) 

@RajeshRadha if you'd like to add the model, feel free to open a PR and tag @ArthurZucker and myself for review. <|||||>Just for reference, before the model got so popular, #22848 and #23849 were opened!
