perf/x86: Add 3 new scheduling callbacks
This patch adds 3 new PMU model specific callbacks
during the event scheduling done by x86_schedule_events().
->start_scheduling(): invoked when entering the schedule routine.
->stop_scheduling(): invoked at the end of the schedule routine
->commit_scheduling(): invoked for each committed event
To be used optionally by model-specific code.
