perf: Add generic exclude_guest support
Only KVM knows the exact time when a guest is entering/exiting. Expose
two interfaces to KVM to switch the ownership of the PMU resources.
All the pinned events must be scheduled in first. Extend the
perf_event_sched_in() helper to support extra flag, e.g., EVENT_GUEST.
