OvmfPkg: pull in SMM-based variable driver stack
When -D SMM_REQUIRE is given, replace both
- OvmfPkg/QemuFlashFvbServicesRuntimeDxe/FvbServicesRuntimeDxe.inf and
- OvmfPkg/EmuVariableFvbRuntimeDxe/Fvb.inf
with
- OvmfPkg/QemuFlashFvbServicesRuntimeDxe/FvbServicesSmm.inf.
The outermost (= runtime DXE driver) VariableSmmRuntimeDxe enters SMM, and
the rest:
- the privileged half of the variable driver, VariableSmm,
- the fault tolerant write driver, FaultTolerantWriteSmm,
- and the FVB driver, FvbServicesSmm,
work in SMM purely.
We also resolve the BaseCryptLib class for DXE_SMM_DRIVER modules, for the
authenticated VariableSmm driver's sake.
