Laszlo Ersek 2590861a5b OvmfPkg/BdsPlatform: don't restore NvVars from disk when flash is present
QemuFlashFvbServicesRuntimeDxe provides actual persistent storage for
non-volatile variables. When it is active, any on-disk NvVars file counts
as a stale source of variables -- hence don't load these files in BDS.

This also allows Secure Boot settings (eg. enrolled keys) to survive cold
VM reboots.

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 d48ec970ad OvmfPkg/build.sh: Enable flash for QEMU >= 1.6
If the QEMU version is found to be >= 1.6, then automatically
enable flash (using the QEMU pflash command line parameter).

QEMU supports flash since 1.2, but only if KVM is disabled.
As of QEMU 1.6, flash support should also be enabled when
KVM is used. Therefore it is safest to only enable flash for
QEMU 1.6 and newer.

Jordan Justen bc9be821c7 OvmfPkg/build.sh: Support --enable-flash switch
If this argument is used, then when QEMU is run, the -pflash
parameter will be used with QEMU to enable QEMU's flash
mode.

It should be used before the 'qemu' argument, since it is
not a QEMU parameter, but instead it updates how build.sh
runs QEMU.

Jordan Justen 182eb45627 OvmfPkg: Add QemuFlashFvbServicesRuntimeDxe to firmware image
This driver will support a flash FVB implementation if QEMU flash
is detected.

The driver is added to the apriori list to make sure it runs
before the EmuVariableFvbRuntimeDxe driver. If this driver detects
flash support, then it will disable the EmuVariableFvbRuntimeDxe
driver by setting PcdFlashNvStorageVariableBase64.
