This was long overdue, allows to access the full feature set of our
kernel for some tools using the Linux API directly.
Packaging mostly taken from Debian[0]

Since Ubuntu Eoan the kernel compression was changed from GZIP to
LZ4, due to slightly faster load times vs. a 25% size increase
trade-off (e.g. 5.0 had ~ 8, this one has ~ 12 MB; *but* the initrd
stays roughly the same size, and that one is 5 times bigger anyway)
If we want to keep that is in the stars, but for now correctly
document the build-dependency to LZ4.

from Depends to Recommends, since we now have an alternate bootloader
setup for some scenarios. both our installer and Debian's default setup
still install Grub by default anyway, but this allows removal without
hacks in case such an alternate bootloader is used on the system.

RETPOLINE is now for sure included, further as this is build through
buildpackage the build dependencies are checked

with the help of "dpkg-checkdep" to mimic the current build-environment
asciidoc-base: used by perf man pages
automake: used by ZFS/SPL (among other things)
cpio: used in debian/rules
debhelper: used in debian/rules
kmod: used in debian/rules (depmod)
libdw-dev,libelf-dev: used for unwinder
libnuma-dev: used by perf
libslang2-dev: used by perf tui
python-minimal: used by perf
zlib1g-dev: used by perf
thank you Thomas for additional review and extensive discussions
regarding what to include (or not ;))!
