x86/pmu: Iterate over adaptive PEBS flag combinations

Iterate over all possible combinations of adaptive PEBS flags, instead of
simply testing each flag individually.  There are currently only 16
possible combinations, i.e. there's no reason not to exhaustively test
every one.

Opportunistically rename PEBS_DATACFG_GP to PEBS_DATACFG_GPRS to
differentiate it from general purposes *counters*, which KVM also tends to
abbreviate as "GP".
