cd99d07d53 OvmfPkg/QemuFlashFvbServices: factor out SetPcdFlashNvStorageBaseAddresses 
Extract the dynamic setting of the
- PcdFlashNvStorageVariableBase64
- PcdFlashNvStorageFtwWorkingBase
- PcdFlashNvStorageFtwSpareBase
addresses to a helper function.

For now, the helper function is identical (duplicated) between the SMM
flash driver and the runtime DXE flash driver. In subsequent patches, this
will change.

3b3d016b7b OvmfPkg/QemuFlashFvbServicesRuntimeDxe: Do not expose MMIO in SMM build 
In the SMM build, only an SMM driver is using the address range hence we
do not need to expose the flash MMIO range in EFI runtime mapping.

b963ec494c OvmfPkg: QemuFlashFvbServicesRuntimeDxe: adhere to -D SMM_REQUIRE 
When the user requires "security" by passing -D SMM_REQUIRE, and
consequently by setting PcdSmmSmramRequire, enforce flash-based variables.

Furthermore, add two ASSERT()s to catch if the wrong module were pulled
into the build.
