Native LIKWID Instrumentation

[lukastruemper]

PR for supporting LIKWID instrumentation in DaCe. The implementation is self-contained in the sense that it does not need to be wrapped by the likwid-perfctr tool.

The available groups (events + metrics) for each architecture can be found in likwid's groups folder, e.g. Skylake

In general, looks good. Your PR removed an important feature from instrumentation reporting, though, and the sample / feature is not documented enough.

[tbennun]

Looking much better! Minor comments remain.

Okay, we're now following stricter contribution guidelines. That's good, the better things can be understood by new people, the better for us

[tbennun]

LGTM!
