perf metrics: Wire up core_wide

Browse Source 
Pass state necessary for core_wide into the expression parser. Add
system_wide and user_requested_cpu_list to perf_stat_config to make it
available at display time. evlist isn't used as the
evlist__create_maps, that computes user_requested_cpus, needs the list
of events which is generated by the metric.
