These changes enable building systemd uki images which combine
kernel, kernel command line, initrd and possibly signatures to
a single UEFI binary. This binary can be booted with UEFI firmware
and systemd-boot. No grub is needed and UEFI firmware and/or
systemd-boot provide possibilities for boot menus.
The uki binary can also be signed for UEFI secure boot
so the secure boot extends from firmware to kernel and initrd.
Binding secure boot to full userspace is then easier since for example
kernel command line and initrd contain the support needed to mount
encrypted dm-verity etc partitions, and/or create partitions on demand
with systemd-repart using device specific TPM devices for encryption.

Tested on qemuarm64-secureboot machine from meta-arm with changes to
support secure boot. Slightly different configuration tested on
multiple arm64 System Ready boards with UEFI firmware, real and firmware
based TPM devices. Tested with ovmf firmware on x86_64 with selftests but
without secure boot which seems to be harder to setup in ovmf.

Sadly I see two wic selftests, wic.Wic2.test_rawcopy_plugin_qemu and
wic.Wic2.test_expand_mbr_image, failing when executing all wic selftests
on a build machine with zfs filesystem. Will investigate this further.
The issue seems to be in mkfs.ext4 producing broken filesystem, and partially
in the tests which don't run the correct rootfs file (.ext4 vs .wic).
Will debug this further and it is IMO unrelated to these changes since
they reproduce on pure master branch without this series.

v3: rebased, fixed and added more sefltests, removed wic plugin side uki
support
