perf kvm: Move up metrics helpers

This patch moves up the helper functions of event's metrics for later
adding code to call them.

No any functionality changes, but has a function renaming from
compare_kvm_event_{metric}() to cmp_event_{metric}().

Committer notes:

Those helper functions are only used if this is true:

  if defined(HAVE_KVM_STAT_SUPPORT) && defined(HAVE_LIBTRACEEVENT)

So keep them enclosed with that.
