[Feature]: Support image embeddings as input for qwen2vl

[whyiug]

🚀 The feature, motivation and pitch

Most multimodal models support input image embeddings. see previous pr: #6613
IMO there's no reason not to support qwen2vl.

When I was about to add this feature to qwen2vl. Unfortunately, I've run into some difficulties.
For example, I can't just rely on image embedding to generate new prompt_token_ids without the original image. See here

height, width = get_image_size(image, channel_dim=input_data_format)

And here, if we just return image embeds, it will occur an error. AssertionError: mrope embedding type requires multi-modal input mapper returns 'image_grid_thw' or 'video_grid_thw'.

Might we need to passthrough more parameters for qwen2vl? please me give some tips.
here is my draft code: #8856
