sim: Add typedefs for PMU probe points

In order to show make PMU probe points usable across different PMU
implementations, we want a common probe interface. This patch the
namespace ProbePoins that contains typedefs for probe points that are
shared between multiple SimObjects. It also adds typedefs for the PMU
probe interface.
