cpu: Create a PCEventScope class to abstract the scope of PCEvents.

This abstraction will allow scheduling PCEvents for a particular
ThreadContext, all contexts on a CPU, all contexts in a system, etc.,
and delegates scheduling and removing events to each particular scope.

Right now the PCEventQueue is the only implementor of the PCEventSCope
interface.
