Subject: [PATCH 08/26] perf vendor events: Update metrics for IcelakeX

Based on TMA_metrics-full.csv version 4.3 at 01.org:
    https://download.01.org/perfmon/
Events are updated to version 1.11:
    https://download.01.org/perfmon/ICX
Json files generated by:
    https://github.com/intel/event-converter-for-linux-perf

Tested:
...
  6: Parse event definition strings                                  : Ok
  7: Simple expression parser                                        : Ok
...
  9: Parse perf pmu format                                           : Ok
 10: PMU events                                                      :
 10.1: PMU event table sanity                                        : Ok
 10.2: PMU event map aliases                                         : Ok
 10.3: Parsing of PMU event table metrics                            : Ok
 10.4: Parsing of PMU event table metrics with fake PMUs             : Ok
...
 68: Parse and process metrics                                       : Ok
...
 88: perf stat metrics (shadow stat) test                            : Ok
 89: perf all metricgroups test                                      : Ok
 90: perf all metrics test                                           : FAILED!
 91: perf all PMU test                                               : Ok
...

Test 90 failed due to MEM_PMM_Read_Latency as the test machine
lacks optane memory, and the divide by 0 causes the metric not to
print - which is intended behavior.

Note: On all current platforms this event stops counting during 'throttling (TM)' states duty off periods the processor is 'halted'.  The counter update is done at a lower clock rate then the core clock the overflow status bit for this counter may appear 'sticky'.  After the counter has overflowed and software clears the overflow status bit and resets the counter to less than MAX. The reset value to the counter is not clocked immediately so the overflow status bit will flip 'high (1)' and generate another PMI (if enabled) after which the reset value gets clocked into the counter. Therefore, software will get the interrupt, read the overflow status bit '1 for bit 34 while the counter value is less than MAX. Software should ignore this case.",
