This patchset adds proper SBOM generation in the two standard formats
SPDX and CycloneDX during the rootfs generation process.

The generation is itself is handled by a SBOM generator  `debsbom` [1]
which is developed as an open source project at Siemens. It is still
early in development, but it has enough features for what we require
in isar. The required dependencies which are not yet available as
Debian packages were minimally packaged directly in isar too.

This is a followup of the previous RFC [2]. Since then the series has
changed a lot. The SBOM generation was moved from a simple OE lib to
`debsbom`. This also meant the introduction of a separate chroot was
necessary. The SBOM generation process was also moved from the image
step to the rootfs step, along with a lot of minor changes and
improvements.

Changes since v1:

- remove tarball
- refactor packaging (auto-derive python dependencies)
- only build missing packages (varies on bookworm, trixie, noble)
- add ubuntu support
- only generate sboms for supported distributions (bookworm/jammy and
  onwards)
- update debsbom (includes bug fixes and more information for source
  packages)
