Move from [PcdsFixedAtBuild, PcdsPatchableInModule] to [PcdsFixedAtBuild, PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx].
This will allow a platform to set this PCD dynamically if it knows how many logical processors the system has. The CpuDxe driver can then use this information during multiprocessor initialization to know that all of the application processors have started.
