Extend `perf test` with additional test cases

[Boursler]

To complement development of PMU events, extend perf test to include tests of sanity of PMU. Suggested tests:

9: Parse perf pmu format
10: PMU events
10:1: PMU event table sanity
10:2: PMU event map aliases
10:3: Parsing of PMU event table metrics
10:4: Parsing of PMU event table metrics with fake PMUs

Add to main driver application for CLI/GUI access to these tests.

I'll have to implement subtests for this. I'll also implement skipped tests with an enum (or something) just like the real perf test
