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.
