Subject: [edk2-devel] [PATCH 1/4] UefiPayloadPkg: Add Fixed PCDs and use Macro to define the default value.

Add the three PCDs as fixed at build PCD:
gEfiMdeModulePkgTokenSpaceGuid.PcdMaxSizeNonPopulateCapsule
gPcAtChipsetPkgTokenSpaceGuid.PcdRtcIndexRegister
gPcAtChipsetPkgTokenSpaceGuid.PcdRtcTargetRegister
The default value is defined as Macro, so it can be passed in at build command.
