This PR introduces a time-based profiler for the SOFIE inference engine. It provides developers with the tools to analyze the performance of generated C++ models by measuring the execution time of each individual operator, as well as the total inference time.
Changes or fixes:
A new option, SOFIE::Options::kProfile, is added to the RModel::Generate() method to enable the feature.
When enabled, a new RModelProfiler helper class instruments the generated doInfer() method with std::chrono timers.
Utility functions like PrintProfilingResults() and GetOpAvgTime() are added to the generated Session struct to access the collected timing data.
Checklist:
Tested changes locally by running inference in a loop and verifying the timing results.
updated the docs (if necessary)
This PR adds a tutorial for the new SOFIE RModelProfiler.
This work continues the development started in PR #19829.
