The PcdDxe dynamic PCD driver is dispatched explicitly via an 'A PRIORI'
declaration in the platform DSC. Without that declaration, the DXE driver
can never be dispatched since it transitively depends on protocols it
produces itself via DxePcdLib. So use the NULL PcdLib explicitly only for
this driver.
