KVM: selftests: Add defines for AMD PMU CPUID features and properties

Browse Source 
Add macros for AMD's PMU related CPUID features.  To make it easier to
cross reference selftest code with KVM/kernel code, use the same macro
names as the kernel for the features.

For reference, the AMD APM defines the features/properties as:

  * PerfCtrExtCore (six core counters instead of four)
  * PerfCtrExtNB (four counters for northbridge events)
  * PerfCtrExtL2I (four counters for L2 cache events)
  * PerfMonV2 (support for registers to control multiple
    counters with a single register write)
  * LbrAndPmcFreeze (support for freezing last branch recorded stack on
    performance counter overflow)
  * NumPerfCtrCore (number of core counters)
  * NumPerfCtrNB (number of northbridge counters)
