perf vendor events: Add Skylake server uncore event list
Add JSON uncore events for Skylake Server to perf. Based on JSON list V1.01 This is a much fuller list than with earlier uncores, including more low level (but also harder to understand) events. It does not include the "experimential" events. The previous high level metric (LLC_* etc.) are still available when applicable. C state power events are not included at this point.
