Laszlo Ersek 9d35ac2611 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.

Jordan Justen a4ce9ffd47 OvmfPkg: Add QemuFlashFvbServicesRuntimeDxe driver 
If QEMU flash is detected, this module will install
FirmwareVolumeBlock support for the QEMU flash device.

It will also set PCDs with the results that:
1. OvmfPkg/EmuVariableFvbRuntimeDxe will be disabled
2. MdeModulePkg variable services will read/write flash directly
