IntelSiliconPkg: Move MicrocodeUpdate from UefiCpuPkg
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.
