    UefiCpuPkg/CpuCommonFeaturesLib: Use MSR data structure when change MSR value.
    
    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.
