Remove unnecessary constants for > 2GB ONNX models

[fxmarty]

e.g.

(hf-inf) fxmarty@huggingface:~/qwen_onnx$ ls
added_tokens.json       merges.txt                                                   model.onnx               tokenizer_config.json
config.json             _model_layers.0_self_attn_rotary_emb_Constant_5_attr__value  model.onnx_data          tokenizer.json
generation_config.json  _model_layers.0_self_attn_rotary_emb_Constant_attr__value    special_tokens_map.json  vocab.json

_model_layers.0_self_attn_rotary_emb_Constant_5_attr__value and _model_layers.0_self_attn_rotary_emb_Constant_attr__value are actually in model.onnx_data already.
