OvmfPkg/QemuKernelLoaderFsDxe: add support for new Linux initrd device path

Browse Source 
Linux v5.7 will introduce a new method to load the initial ramdisk
(initrd) from the loader, using the LoadFile2 protocol installed on a
special vendor GUIDed media device path.

Add support for this to our QEMU command line kernel/initrd loader.
