MULTIARCH-4559: config/v1/types_cluster_version.go: Add 'architecture' to the release structure

[wking]

As requested in the enhancement. Motivation for the new property from the enhancement:

There were a few options discussed in lieu of introducing a new ClusterVersion status field and the potential risks for doing so. The alternatives are highlighted with reasoning given for why they were not pursued:

• Default ImportMode to PreserveOriginal everywhere: single-arch-release users maybe concerned about import size and the lack of metadata like dockerImageLayers and dockerImageMetadata for manifestlisted imagestream tags.
• Clusters with homogeneous nodes running the multi payload who do not want to import manifestlists: The clusters can either migrate to single arch payloads or manually toggle the importMode through the image config CRD.
• CVO provides architecural knowledge to the cluster-image-registry-operator through a configmap or the image config CRD: To limit the risk of many external consumers using CVO's status field to determine that their cluster is multi-arch ready, the idea was to expose this information to the specific controller. This solution is not necessary as we let other controller implementers decide if the CVO's new status field is the best fit for their use case.
