OvmfPkg: clone NorFlashPlatformLib into VirtNorFlashPlatformLib

Create a new library class in Ovmf that duplicates the existing
NorFlashPlatformLib, but which will be tied to the VirtNorFlashDxe
driver that will be introduced in a subsequent patch. This allows us to
retire the original from ArmPlatformPkg.
