need a way to add foreign architecture to sources.list for build-packages/stage-packages
Metadata
Current evaluation
Foreign-architecture build- and stage-packages still fail in Launchpad chroots; a 2023 core22 arm64 reproducer confirms the requested repository setup remains unresolved.
Suggested action: keep open
Reason: A concrete core22 reproducer still reports that an available arm64 stage package cannot be installed, and the later comment says the problem remains despite tooling support. Keep it open as a valid bug, while further triage should define the intended automatic configuration and whether the newer target-repository approach fully replaces it.

Issue body
If I specify:
parts:
foo:
build-packages:
- on arm64: ["bar:armhf"]
then the build will fail in LP with something like:
Using 'snapcraft.yaml': Project assets will be searched for from the 'snap' directory.
Could not find a required package in 'build-packages': foo:armhf
Build failed
This is because the LP chroot for arm64 by design doesn't have foreign architecture support and there are no armhf lines configured in sources.list. I would expect that specifying "foo:i386" would update the build environment as necessary on amd64 so the package is installable, and the same for "foo:armhf" with arm64.
This would be useful for stage-packages as well.
I ran into this because I was trying to build some binaries with -m32 on arm64 and needed gcc-multilib. gcc-multilib is only available in the Ubuntu archive with "gcc-multilib:armhf", but this fails to install in LP using its arm64 chroot.
