Somewhere along the line, we started trying to add packages to the live
environment of flavor "preinstalled" images. But:
- we don't build preinstalled images for any flavors
- the preinstalled images for projects like cloud images and wsl are
explicitly excepted from this code
- the only desktop project we do produce preinstalled images for, Ubuntu
on Raspberry Pi, uses ubuntu-image for building so this code is never
reached
Now that kernel names use expected -generic flavour, and kernels are
installed in the live layer, we can go back to stock behaviour of
auto/build noticing that binary hooks are called on a live layer and
executing the extraction & rename of the kernel flavours.
BTW we can even later expand that to support 2 generic abis, and
calling the bigger one the hwe generic such that can also remove
./live-build/ubuntu-server/hooks/04-kernel-bits.binary.
This fixes ubuntu arm64+x13s that is unable to find
ubuntu-x13s.kernel-laptop as due to this hook, which currently
produces ubuntu.kernel-generic in error which is not at all expected
by ubuntu-cdimage. Also this unbreaks producing oem & intel-iot
images, although we will build these in 24.04 only next.
This reverts ubuntu daily-live to use `--linux-flavours
laptop-generic-hwe-22.04` instead of `--linux-flavours none
--linux-packages=none --initramfs=none`, like it did in lunar and
pre-canary-image or images that install kernel in live layer.

With the migration from linux-kvm to linux-virtual/generic for the mantic minimal
images we can now start building arm64 minimal cloud images.
When building initial test images we noticed that the flash-kernel package was being
installed. This is not required for EFI images.
This commit removes the flash-kernel package from the cloud images arm installs
The only images built using the livecd-rootfs ubuntu-cpc project for arm64 and armhf
which are not cloud images (which therefore do not require flash-kernel) are the
raspi images. raspi does require flash-kernel. But the raspi images use the
`ubuntu-server-raspi` task to install the flash-kernel. As such this non raspi
flash-kernel package install can be completely removed.
It also means that initramfs-tools and dracut-install are installed as these are dependencies
of flash-kernel package.
Add mapping to use laptop-23.10 kernel. Ensure that
enhanced-secureboot is only setup on amd64 arch.

When trying to make changes to refactor livecd-rootfs, it is difficult to
know what side effects a change may have because of the use of globs on
arch/subarch and the lack of an authoritative list of supported arch
combinations.
This assembles a list of all possible values for $ARCH:$SUBARCH by looking at
all existing uses of $SUBARCH in live-build/auto/config and combining with
etc/default-arches from ubuntu-cdimage:
$ grep + etc/default-arches |grep -vE '(trusty|xenial|bionic|focal)[[:space:]]|appliance'
It also includes a special-case *appliance* glob, because there are many
Ubuntu Core appliance builds and there may be more in the future, and we
don't want to have to update livecd-rootfs with a hard-coded list.
Otherwise, this includes all currently used / supported combinations. The
amd64+kassel subarch is referenced in the code, but stopped being built a
while ago because "end of contract"; and there are some older no-longer-used
subarchs for particular raspi variants, which there is work to clean up
separately. So this should be a no-op wrt buildability of any existing
images on mantic - and if not, that's important for us to know!
The pi images contain redundant copies of cmdline.txt and config.txt in
the boot partition mount-point (which get hidden by the *actual* boot
partition). This commit removes those and simplifies the subarch check
(again, +raspi is the only subarch in use at this point on the Raspberry
Pi images)
