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.

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.

Revert incompatible change:
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.
