[ONNX] Fix onnx constant folding (#101329)
Fixes #101328
Note that this most likely is a bandage solution. We either need to actually fix one of those onnx passes that is causing this decomposition/functionalization issue, or need to special case all onnx op in `runTorchBackendForOnnx` like this one.
