b970ed6829 UefiCpuPkg/MtrrLib: Add MtrrSetMemoryAttributeInMtrrSettings() 
Add new API MtrrSetMemoryAttributeInMtrrSettings() in MtrrLib. Platform could
use this API to set MTRR setting into local MTRR settings buffer instead of
MTRRs. At last, platform could use MtrrSetAllMtrrs() to set the MTRR settings
into MTRRs totally. It could improve MTRRs programming performance obviously,
specially when platform is going to program a set of MTRRs.

46309b1101 UefiCpuPkg/MtrrLib: Add PCD PcdCpuNumberOfReservedVariableMtrrs 
Current MtrrLib reserves 2 variable MTRRs for some legacy OS boot (CSM boots)
may require some MTRRs to be reserved for OS use. But UEFI OS boot will not use
MTRRs.

Per Scott's suggestion in
link: http://article.gmane.org/gmane.comp.bios.edk2.devel/4099
Add one PCD PcdCpuNumberOfReservedVariableMtrrs to specify the number of
variable MTRRs reserved for OS use. Setting its default value to 2 is for
back-compatibility.

91ec78241c 1. Introduce the API MtrrGetDefaultMemoryType () in Mtrr Library. 
2. Invoke MtrrGetDefaultMemoryType() to get the default memory type instead of the hard code value in module.
3. Add go though for UC attributes.

1) No API change from old version.
2) Change MACRO:
#define  MTRR_NUMBER_OF_VARIABLE_MTRR  32 // the semantics are changed from NUMBER to MAX_NUMBER.
#define  FIRMWARE_VARIABLE_MTRR_NUMBER  6 // wrong and deprecated
#define  MTRR_LIB_IA32_VARIABLE_MTRR_END 0x20F // wrong and deprecated
#define  RESERVED_FIRMWARE_VARIABLE_MTRR_NUMBER  2 // add new one.
