Add --buildkit flag to use docker buildx build instead of the docker-py SDK. An optional --buildkit-builder selects a named buildx builder instance, enabling docker-container or remote drivers for multi-arch builds. --buildkit and --squash are mutually exclusive and rejected at startup. PushTask is skipped when buildkit is active; push is handled inline. Set buildkit as the new default.

Leaving empty CI template_overrides file in case we need to use it in future. Change-Id: Ic46f1a594bcc330536bc78d93ece10e60622f6d4 Signed-off-by: Michal Nasiadka <mnasiadka@gmail.com>
Repos marked build_only: true are backed up before handle_repos()
overwrites them and restored at the end of each image build, so CI
mirror URLs are not baked into the final image.
The cleanup RUN was injected into every Dockerfile, not just images
that called handle_repos() for those repos. Child images with no
backup fell through to "rm -f", deleting the inherited repo file
(e.g. debian.sources in bifrost-base, breaking cpio install).
Fix by adding a {repo}.enabled sentinel that handle_repos creates
when it processes a build_only repo, making the cleanup conditional
on that sentinel.
