…orch#15413)

Summary:
Pull Request resolved: pytorch#15413

In order to pass arguments to the ios app, need to extarct the arguments
to its own file. Also, in the ios app, do not use the benchmark.json, which
parses the arguments.

This is an incompatible change, needs to add hot fix to the tests.
