* Fix GELU ONNX export

* Wrap GELU export with cast to/from FP32 to achieve same compute precision as TE.
* Increase GELU export test thresholds.
* Change export to ONNX opset 17 for smaller representation of LN (single node instead of subgraph).
* Remove the need for LN work-around for ORT

* Tune threshold for GELU ONNX export

Ran 8K test instances to verify the threshold.
Allow 2 coefficients to escape threshold. Two wrong coefficients
are not a failure.
