Now that we have the cloud-minimal seed for minimized cloud
image builds, we should drop all the workarounds and hacks
we once needed when we were using the server seed. We can
directly use the new metapackage and get rid of the tasks and
other autoremoves, et al.
Revert this change for now as /boot then becomes a FAT partition which
breaks DPKG requirements[1]. This change is going to be re-evaluated and
maybe introduced in a different way.
This is not a clean revert because of 3282efb ("ubuntu-cpc: cleanup
disk-images-uefi.binary") which we want to keep.

Package linux-allwinner has a kernel with the generic flavour as
dependency. Add this translation to our code checking the correct
installation.

Remove kvm-image altogether.
Previously for minimal image replace_kernel function replaced virtual
images with kvm, and called force_boot_without_initramfs. Now simply
call force_boot_without_initramfs for minimal image without replacing
kernel flavour.
This also means minimal images can now be built for arm64 and armhf.

Up to now we have used u-boot-menu for preinstalled images for the SiFive
HiFive Unmatched and Unleashed boards and GRUB for all other RISC-V images.
The choice was made because RISC-V GRUB was not available when the SiFive
boards where released.
Let the Unmatched and Unleashed board preinstalled images use GRUB.
Simplify the code.

Canonical Public Cloud's project seems a bad place to build images for
hardware devices however this is how things were done a we now need to
maintain this.
The recent change to mount the ESP on /boot breaks those images, instead
of adding more hacky things in the hook, create a dedicated target for
those images and use a different hook to build UEFI images.
This is required by the new UEFI binary hook as we mount the ESP on
/boot and the ESP filesystem doesn't support symlinks.
We keep symlinks for s390x images which do not use UEFI anyway.
This is driven by online encryption scenarios. In order to efficiently
encrypt the root filesystem without modifying the partition layout, the
kernel should sit in an un-encrypted /boot partition. Instead of
creating a new partition that would change the default partition layout,
we mount the ESP on /boot. We also need to then bind mount /boot on
/boot/efi because that's where Grub expects the ESP to be located.
