REF: https://bugzilla.tianocore.org/show_bug.cgi?id=540 To consume FIT table for Microcode update, UefiCpuPkg/Feature/Capsule/MicrocodeUpdateDxe needs to be updated to consume IntelSiliconPkg/Include/IndustryStandard/FirmwareInterfaceTable.h, but UefiCpuPkg could not depend on IntelSiliconPkg. Since the Microcode update feature is specific to Intel, we can first move the Microcode update feature code from UefiCpuPkg to IntelSiliconPkg [first step], then update the code to consume FIT table [second step]. This patch series is for the first step. Note: No any code change in this patch, just move. Next patch will update MicrocodeUpdate to build with the package.
