The Konflux CI project has experimented with using Kata peer pods to
run builds on remote VMs with different CPU architectures. This PoC
proved that the Kubernetes fundamentals (use of Kata `RuntimeClass`
pods) work, however there are significant barriers to provisioning and
managing the peer pod VMs. Added this background context and PoC result
to the proposal.

Proposal to extend the `Build` and `BuildRun` APIs to
orchestrate multi-arch container image builds. This is a smaller
version of the original SHIP-0043 proposal [1], and in its
current form only supports the build on native OS/CPU arch nodes.
Using cross-compilation, emulation, or other means of executing
multi-arch container image builds is out of scope.
