perf evlist: Add 'system_wide' option
Add an option to cause a selected event to be opened always without a pid when configured by perf_evsel__config(). This is needed when using the sched_switch tracepoint to follow object code execution. sched_switch occurs before the task switch and so it cannot record it in a context limited to that task. Note that also means that sched_switch is useless when capturing data per-thread, as is the 'context-switches' software event for the same reason.
