OvmfPkg: indicate enablement of flash variables with a dedicated PCD
PcdFlashNvStorageVariableBase64 is used to arbitrate between QemuFlashFvbServicesRuntimeDxe and EmuVariableFvbRuntimeDxe, but even the latter driver sets it if we fall back to it. Allow code running later than the startup of these drivers to know about the availability of flash variables, through a dedicated PCD.
