perf/x86/intel: Rename confusing 'freerunning PEBS' API and implementation to 'large PEBS'
The 'freerunning PEBS' and 'large PEBS' are the same thing. Both of these
names appear in the code and in the API, which causes confusion.
Rename 'freerunning PEBS' to 'large PEBS' to unify the code,
which eliminates the confusion.
No functional change.
