perf pmu: Restructure print_pmu_events() to avoid memory allocations

Previously print_pmu_events() would compute the values to be printed,
place them in struct sevent, sort them and then print them.

Modify the code so that struct sevent holds just the PMU and event, sort
these and then in the main print loop calculate aliases for names, etc.

This avoids memory allocations for copied values as they are computed
then printed.
