Tan, Ming 45bc28172f MdeModulePkg.dec: Change PCDs for status code.
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.
