Bruce Ashfield 6bb1621815 perf: reproducibility fixes for pmu-events.c ...

perf generates pmu-events.c as part of the build process. The
code that generates the events is doing tree walks and potentially
other non-determinstic things.

We'd rather not mess with that implementation, so we add a script
that knows how to read the pmu-events.c, sort the entries and then
copy it over the generated one.

With this, we should always have events in the same order, improving
reproducibility.
