REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2786 In order to support enable/disable report status code through memory or serial dynamic, change the following PCDs from [PcdsFeatureFlag] to [PcdsFixedAtBuild, PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx]: PcdStatusCodeUseSerial PcdStatusCodeUseMemory The original plaforms can use PcdsFixedAtBuild in .dsc files to save size.
