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].

Update the haswellx metrics and events using the new tooling from:
https://github.com/intel/perfmon
The metrics are unchanged but the formulas differ due to parentheses,
use of exponents and removal of redundant operations like "* 1". The
order of metrics varies as TMA metrics are first converted and then
removed if perfmon versions are found. The events are updated with
fixes to uncore events and improved descriptions. The formatting
changes increase consistency across the json files.

This is not a full uncore event list, but a short list of useful and
