UefiCpuPkg: Add NULL CPU Common Features Library instance
This NULL CPU common Features Library instance will register some CPU features
defined in Intel(R) 64 and IA-32 Architectures Software Developer's Manual,
Volume 3, September 2016, Chapter 35 Model-Specific-Registers (MSR).
Add PCD PcdCpuClockModulationDutyCycle and PcdIsPowerOnReset consumed by NULL
CPU Common Features Library instance.
v2:
1. Using MSR_IA32_EFER to enable/disable NX feature instead of using
MSR_IA32_MISC_ENABLE.
2. Fix bug that SMX and VMX feature is swapped.
v3:
1. Add AesniGetConfigData() to get current register state.
v5:
Move MSR reading from AesniGetConfigData() to AesniSupport().
