mtmd : add qwen2vl and qwen2.5vl (#13141)
* llava : add clip_n_output_tokens, deprecate clip_n_patches * mtmd : add qwen2vl and qwen2.5vl * decode_embd_batch::set_position_... * working version * deprecate llama-qwen2vl-cli * correct order W, H of clip_embd_nbytes_by_img * edit existing line in hot topics
