Subject: perf pmus: Remove perf_pmus__has_hybrid

perf_pmus__has_hybrid was used to detect when there was >1 core PMU,
this can be achieved with perf_pmus__num_core_pmus that doesn't depend
upon is_pmu_hybrid and PMU name comparisons. When modifying the
function calls take the opportunity to improve comments,
enable/simplify tests that were previously failing for hybrid but now
pass and to simplify generic code.
