Xen has its own version of the image header, to account for the additional PE/COFF header fields. Since we are adding references to those in the shared EFI loader code, update the common definitions and drop the Xen specific one which no longer has a purpose. Since in both cases, the call to grub_arch_efi_linux_check_image() is preceded by a load of the image header, let's move the load into that function, and rename it to grub_arch_efi_linux_load_image_header().
