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.

MtrrDebugPrintAllMtrrs() should loop until the max physical address is reached.

GetMemoryCacheTypeFromMtrrType () should return the default memory type instead of UC type for MTRR_CACHE_INVALID_TYPE.
