perf pmu-events: Add separate metric from pmu_event

Create a new pmu_metric for the metric related variables from pmu_event
but that is initially just a clone of pmu_event. Add iterators for
pmu_metric and use in places that metrics are desired rather than
events. Make the event iterator skip metric only events, and the metric
iterator skip event only events.
