d460c01b - Fix skew between GPU/CPU timestamps in ORT profiler (#14004)

Fix skew between GPU/CPU timestamps in ORT profiler (#14004) ### Description This PR fixes the skew between GPU/CPU timestamps with a more reliable algorithm. ### Motivation and Context An earlier implementation attempted to guess the right correction to apply, but this led to misleading profile outputs. This PR fixes this problem by utilizing a more reliable technique to normalize GPU timestamps. Attached are sample profile outputs and visualization screen-grabs from a run of a transformer-based model before and after the fix. Before Fix:  After Fix:  Profiler outputs that are rendered in the visualizations above: [sample_outputs.zip](https://github.com/microsoft/onnxruntime/files/10249689/sample_outputs.zip) Co-authored-by: Abhishek Udupa <abhishek.udupa@microsoft.com>
