Introduce bootc-base-imagectl - Embed the manifests into the container image - Add bootc-base-imagectl which is a tightly controlled frontend to execute on those manifests. For now, we don't attempt to rework how we build the standard image to actually look like `dnf install`, but we show that it can work. Signed-off-by: Colin Walters <walters@verbum.org>

# This test case exercises using the fedora-bootc image as a builder
# to generate a minimal target image derived from CentOS Stream 10 content,
# and then further extends it in a secondary phase.
ci: Drop tier-x build, do build test case As part of all of this we're de-emphasizing "tier-x" and focusing on making it ergonomic to either build up from minimal, or down+up from standard. Second, also add a CI test for our derived image. Signed-off-by: Colin Walters <walters@verbum.org>

bootc-base-imagectl: support extending package list The current custom base image flow of rebuilding a "built-in" image with custom repos and then adding your own content separate is reasonable, but it would be nice if one could augment the list of packages to install in that initial build rather than as a separate transaction. Then, you don't have to cleanup after dnf and `/var` content, re-inject repo definitions, and refetch repo metadata. It also allows building container images with additional packages without `dnf` necessarily being in the package set. We don't want to leak rpm-ostree implementation details, nor do we want to invent a new format. So just add support for a `--install` arg and a generic `--args-file` to pass arguments via a file. We then generate a new treefile on the fly to extend the `packages` list.
