perf: Complete software pmu grouping
Aside from allowing software events into a !software group,
allow adding !software events to pure software groups.
Once we've moved the software group and attached the first
!software event, the group will no longer be a pure software
group and hence no longer be eligible for movement, at which
point the straight ctx comparison is correct again.
