perf/x86/intel/ds: Add PEBS format 6
The only difference between 5 and 6 is the new counters snapshotting
group, without the following counters snapshotting enabling patches,
it's impossible to utilize the feature in a PEBS record. It's safe to
share the same code path with format 5.
Add format 6, so the end user can at least utilize the legacy PEBS
features.
