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.

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.

The LocalApicLib does not provide a function to manage the state of the

are cases where this bit needs to be managed without side effects to.
