perf vendor events intel: Add umasks/occ_sel to PCU events.

UMasks were being dropped leading to all PCU
UNC_P_POWER_STATE_OCCUPANCY events having the same encoding. Don't
drop the umask trying to be consistent with other sources of events
like libpfm4 [1]. Older models need to use occ_sel rather than umask,
correct these values too. This applies the change from [2].
