In an upcoming patch, we will introduce a separate DXE driver that exposes the virtual SimpleFileSystem implementation that carries the kernel and initrd passed via the QEMU command line, and a separate library that consumes it, to be incorporated into the boot manager.
Since the GUID used for the SimpleFileSystem implementation's device path will no longer be for internal use only, create a well defined GUID to identify the media device path.
