Save PyTorch profile data to CSV

[kgajdamo]

Enable to save pytorch profiling results to csv (top 5 most time consuming ops).

• The --write-csv argument has been modified so that it can now take three values:
  None (do not write data to csv)
  bench (write benchmark data to csv)
  prof (write pytorch profiler data to csv)
• Added new argument --export-chrome-trace, that enables to export chrome trace file (defaults to true).

Example command to profile with pytorch and save results to csv:
python ./inference_benchmark.py --profile --write-csv prof --export-chrome-trace False
