78469533 - [ONNX] Constant folding to not add folded constant as initializer (#79552)

[ONNX] Constant folding to not add folded constant as initializer (#79552) Previous behavior adds all folded values as initializers(model parameters). Now only add folded values as initializers, if the original values were initializers.
