Add Qwen2.5VL support

[HimariO]

Original issue: #11483

Changes

• Add new gguf key for clip model to support
  • GLU MLP,
  • window attention,
  • RMS norm
• Updated clip.cpp vision model to incorporate these new components.
• Modified qwen2_vl_surgery.py and convert_hf_to_gguf.py to support the Qwen2.5VL model.

Model Conversion

The only change in the conversion process compared to Qwen2VL is the addition of the model_type parameter when creating the vision encoder GGUF file. (For the rest of the process and how to build llama-qwen2vl-cli, refer to #10361.)

PYTHONPATH=$PYTHONPATH:$(pwd)/gguf-py python3 examples/llava/qwen2_vl_surgery.py "/path/to/model" --data_type fp16 --model_type "qwen2.5vl"
