PeiSmbusLib & DxeSmbusLib

Remove Arp Related interfaces
	Change the return type of SmbusQuickWrite from “BOOLEAN” to “VOID”
	Complete interface SmBusBlockProcessCall()
	Make the PEC bit “bit 21” of SMBUS address. If data show that MSB helps to save code size in BaseSmbusLib, we may simply redefine it to be MAX_BIT.
UefiLib
	Modify the interfaces in UefiNotTiano.c to sync with spec
MemoryAllocationLib
	Add extra checking in “Aligned” Memory services to prevent “AllocationSize + OverAllocation” overflow in DxeMemoryAllocationLib.
