The following PCDs have no value in UefiPayloadPkg.dsc，and they can not pass the Ecc tool check, so assign the default values the same as they are in *.dec file.
gEfiMdeModulePkgTokenSpaceGuid.PcdAriSupport
gEfiMdeModulePkgTokenSpaceGuid.PcdMrIovSupport
gEfiMdeModulePkgTokenSpaceGuid.PcdSrIovSupport
gEfiMdeModulePkgTokenSpaceGuid.PcdSrIovSystemPageSize
gUefiCpuPkgTokenSpaceGuid.PcdCpuApInitTimeOutInMicroSeconds
gUefiCpuPkgTokenSpaceGuid.PcdCpuApLoopMode
gUefiCpuPkgTokenSpaceGuid.PcdCpuMicrocodePatchAddress
gUefiCpuPkgTokenSpaceGuid.PcdCpuMicrocodePatchRegionSize
