Fusilli <> tuner v1: Add IREE tuner integration via Python wrapper script

[bangtianliu]

This PR adds benchmarks/run_tuner.py, a Python wrapper around amdsharktuner.libtuner that lets non-expert users invoke the IREE tuner directly from Fusilli.

Issue: #255

I think this is a useful next step but I am pretty confused why you'd want to integrate it at the fusilli core layer when all the direct consumers of this will be at the fusilli provider layer. That's the main user facing interface for fusilli (via hipdnn) and this fits there. @AaronStGeorge could you share what would be a good interface point and next steps to get this integrated properly?

Thanks for the pointer, that link is helpful. You're right, the mistake on my end came from a lack of context about where fusilli is actually used.
