perf jevents: Add cpuid to model lookup command

When restricting jevents generated json lookup code with JEVENTS_MODEL
a list of models must be provided. Some builds don't know model names
but know cpuids. Add a command that can convert a cpuid to a model
using mapfile.csv files. This can be used with JEVENTS_MODEL like:

  $ make JEVENTS_MODEL=`./pmu-events/models.py x86 'GenuineIntel-6-8D-1,AuthenticAMD-26-1' pmu-events/arch/`

Committer testing:

  $ tools/perf/pmu-events/models.py x86 'GenuineIntel-6-8D-1,AuthenticAMD-26-1' tools/perf/pmu-events/arch/
  tigerlake,amdzen5
  $ perf stat -v sleep 1 |& head -1
  Using CPUID GenuineIntel-6-B7-1
  $ tools/perf/pmu-events/models.py x86 'GenuineIntel-6-B7-1' tools/perf/pmu-events/arch/
  alderlake
