Add qwen2-vl HF GPU example

[ATMxsp01]

• Add support for ipex_llm.transformers.Qwen2VLForConditionalGeneration
• Add Qwen2-VL GPU examples with from_pretrained

[Oscilloscope98]

Refer to https://github.com/modelscope/modelscope/blob/master/requirements/datasets.txt, we may have a try on
pip install modelscope[datasets]==1.21.0, as it includes addict simplejson python-dateutil sortedcontainers

[Oscilloscope98]

Let's use What is in the image? and 图片里有什么？ as the sample prompts to make it consistent with other examples. And move Chinese prompt to the 1st sample output.
