Ruiyu Ni 60cb4d1b04 UefiCpuPkg/CpuCommonFeatures: Follow SDM for MAX CPUID feature detect
According to IA manual:
"Before setting this bit (MSR_IA32_MISC_ENABLE[22]) , BIOS must
execute the CPUID.0H and examine the maximum value returned in
EAX[7:0]. If the maximum value is greater than 2, this bit is
supported."

We need to fix our current detection logic to compare against 2.

Ruiyu Ni dc7363f848 UefiCpuPkg/FeaturesLib: don't init MCi_CTL/STATUS when MCA's disabled
Today's McaInitialize() doesn't check State value before initialize
MCi_CTL and MCi_STATUS.
The patch fixes this issue by only initializing the two kinds of
MSRs when State is enabled.

Ruiyu Ni 0c8b880223 UefiCpuPkg/FeaturesLib: Fix Haswell CPU hang with 50% throttling
Today's implementation only assumes SandyBridge CPU supports
Extended On-Demand Clock Modulation Duty Cycle.
Actually it is supported when CPUID.06h.EAX[5] == 1.

When platform requests 50% throttling, it causes value 1000b
set to the low-4 bits of IA32_CLOCK_MODULATION.
But the wrong code sets 1000b to bits[1-3] which causes assertion.

     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().
