Yan, Zheng 63f0c1d841 perf/x86/intel: Track number of events that use the LBR callstack
When enabling/disabling an event, check if the event uses the LBR
callstack feature, adjust the LBR callstack usage count accordingly.
Later patch will use the usage count to decide if LBR stack should
be saved/restored.
