[ONNX] Update value name copying logic for onnx (#66170) (#67275)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/67275
Specifically targets the symbolic functions that directly returns input as output. The old logic will override the value name with output value name. But since the input is unmodified and unchanged, it is more logically to keep its original input name. Especially for cases where inputs are directly from model parameters.
