For dynamicEx type PCD, it is compatible between PCD_PPI and EFI_PEI_PCD_PPI. This library instance uses the PCD_PPI to handle dynamic PCD request and use EFI_PEI_PCD_PPI to handle dynamicEx type PCD. This library instance assumes that PCD_PPI and EFI_PEI_PCD_PPI are both installed early. The PCD Library that uses the PCD PPI to access Dynamic and DynamicEx PCD entries."
