24f0893d - Enable optimize_by_onnxruntime call for float32 unet model (#17483)

Enable optimize_by_onnxruntime call for float32 unet model (#17483) This makes it possible to call `optimize_by_onnxruntime` for float32 unet if `--use_external_data_format` is also used. ### Motivation and Context When using `optimize_pipeline.py` without `--float16`, `optimize_by_onnxruntime` was not called for unet.
