perf tools: Extend format_alias() to include event parameters
perf tools: Extend format_alias() to include event parameters

This causes `perf list pmu` to show parameters for parameterized events
like:

  pmu/event_name,param1=?,param2=?/ [Kernel PMU event]

An example:

  hv_24x7/HPM_TLBIE__PHYS_CORE,core=?/ [Kernel PMU event]
