Laszlo Ersek 6d7af0c9bc OvmfPkg/EmuVariableFvbRuntimeDxe: always format an auth varstore header 
In this patch, we extend commit d92eaabefb ("OvmfPkg: simplify
VARIABLE_STORE_HEADER generation", 2016-02-05) to
EmuVariableFvbRuntimeDxe.

This is the difference between FvAndVarTemplate and
FvAndAuthenticatedVarTemplate:

After this change, using "-bios", the variable driver logs:

- with the SB feature enabled:
> Variable driver will work with auth variable format!
> Variable driver will work with auth variable support!

- with the SB feature disabled:
> Variable driver will work with auth variable format!
> Variable driver will continue to work without auth variable support!

jljusten 670d495b19 Add EmuVariableFvbRuntimeDxe driver. 
This driver implements a firmware volume block protocol instance
which is stored in system memory.

The MdeModulePkg/Universal/Variable/RuntimeDxe and
MdeModulePkg/Universal/FaultTolerantWriteDxe drivers make use of
this FVB instance to provide variable services.

This driver links to a PlatformFvb library to allow for
platform specific processing to take place when data is written
to the FVB.
