x86,fs/resctrl: Fill in details of events for performance and energy GUIDs

The telemetry event aggregators of the Intel Clearwater Forest CPU support two
RMID-based feature types: "energy" with GUID 0x26696143¹, and "perf" with
GUID 0x26557651².

The event counter offsets in an aggregator's MMIO space are arranged in groups
for each RMID.

E.g., the "energy" counters for GUID 0x26696143 are arranged like this:

  MMIO offset:0x0000 Counter for RMID 0 PMT_EVENT_ENERGY
  MMIO offset:0x0008 Counter for RMID 0 PMT_EVENT_ACTIVITY
  MMIO offset:0x0010 Counter for RMID 1 PMT_EVENT_ENERGY
  MMIO offset:0x0018 Counter for RMID 1 PMT_EVENT_ACTIVITY
  ...
  MMIO offset:0x23F0 Counter for RMID 575 PMT_EVENT_ENERGY
  MMIO offset:0x23F8 Counter for RMID 575 PMT_EVENT_ACTIVITY

After all counters there are three status registers that provide indications
of how many times an aggregator was unable to process event counts, the time
stamp for the most recent loss of data, and the time stamp of the most recent
successful update.

  MMIO offset:0x2400 AGG_DATA_LOSS_COUNT
  MMIO offset:0x2408 AGG_DATA_LOSS_TIMESTAMP
  MMIO offset:0x2410 LAST_UPDATE_TIMESTAMP

Define event_group structures for both of these aggregator types and define
the events tracked by the aggregators in the file system code.

PMT_EVENT_ENERGY and PMT_EVENT_ACTIVITY are produced in fixed point format.
File system code must output as floating point values.
