Add option to execute model from explorer

[odjuricicTT]

This might require changes in ttrt in order to be able to use ttrt.API.perf.

@vprajapati-tt What do you think about adding --output-file (or similar) to ttrt perf, in other to not have to parse the output of a subprocess?

Hey! I just saw this, a while back I added the --artifact-dir option when running perf. TTRT itself outputs the log to a file (if specified) and also stdin. The issue with Perf is that TTRT ends up using signal to look for SIGINT and SIGTERM from Tracy. Since model-explorer is run in a thread (or process), this isn't well received by python and it either crashes or doesn't detect these signals. I played around with this for a while and circled back to using a subprocess since that was the simplest method to get a prototype working.

I'd be interested to revisit this as there's probably something I'm missing that can solve this problem. Let me know if there's anything else I can clarify.

Got it! Thanks for the info, we'll take a look if there is a good way to solve this. If not we will stick with a subprocess then.
