perf evsel: Add function to compute group PMU name
The computed name respects software events and aux event groups, such
that the pmu_name is changed to be that of the aux event leader or
group leader for software events. This is done as a later change will
split events that are in different PMUs into different groups.
Committer notes:
Added a stub for this new function so that 'perf test python' passes.
