perf vendor events intel: Alderlake/rocketlake metric fixes

Fix that the core PMU is being specified for 2 uncore events. Specify
a PMU for the alderlake UNCORE_FREQ metric.

Conversion script updated in:

  https://github.com/intel/perfmon/pull/126

Committer testing:

Before this patch the "perf all metricgroups test" was failing, now:

  root@number:~# perf test metric
   10: PMU events                                                      :
   10.3: Parsing of PMU event table metrics                            : Ok
   10.4: Parsing of PMU event table metrics with fake PMUs             : Ok
   10.5: Parsing of metric thresholds with fake PMUs                   : Ok
   61: Parse and process metrics                                       : Ok
   98: perf stat metrics (shadow stat) test                            : Skip
  101: perf all metricgroups test                                      : Ok
  102: perf all metrics test                                           : FAILED!
  107: perf metrics value validation                                   : Ok
  root@number:~#

Test 102 is failing for another reason, not being able to get as many
counters as needed, Ian Rogers suggested disabling the NMI watchdog to
have more counters available:

  root@number:/home/acme# cat /proc/sys/kernel/nmi_watchdog
  1
  root@number:/home/acme# echo 0 > /proc/sys/kernel/nmi_watchdog
  root@number:/home/acme# perf test 102
  102: perf all metrics test                                           : Ok
  root@number:/home/acme#
