With correct model CPU, current checking logic will
always execute AsmReadMsr64 operation and then check
ECX.AESNI[bit 25] = 1. Update checking logic to check
ECX.AESNI[bit 25] = 1 first and then do AsmReadMsr64
operation.

The ConfigData parameter initialized in *GetConfigData function should not be NULL in
later *Support, *Initilize function, so just add ASSERT code check in these functions.

Original code about Local Machine Check exception feature saves in a
discrete file, because features related to machine check architecture
all saved in MachineCheck.c file. This patch moved LMCE logic to same
file for easy maintenance.

The EnumProcTraceMemDisable/OutputSchemeInvalid are redundant
definitions. These definitions can be handled by other code,
so remove them.
V2: Change enum members name.

When update MSR values, current code use BITxx to modify it. Enhance the code
to use corresponding MSR's data structures to make it more user friendly.
V2: Move architecturalMsr.h file. definition to architecturalMsr.h file.
Use structure members to do value assignment.

Current X2APIC is enabled in MpInitLib (used by CpuMpPei and CpuDxe) to follow
SDM suggestion. That means we only enable X2APIC if we found there are any
initial CPU ID value >= 255.
This patch is to provide one chance for platform to enable X2APIC even there is
no any initial CPU ID value >= 255.
