A manual backport of #1291 due to conflicts in the pkg/cvo/availableupdates_test.go file when applying the availableupdates_test: Add test cases for spec.DesiredUpdate commit.

The osusWithSingleConditionalEdge logic was broken down into smaller
parts to allow for the creation of list of test cases with expected
values utilized in the added test function.

Introduce a test fixture to reduce the number of return values
from the osusWithSingleConditionalEdge function.

Assisted-by: Claude Code
Otherwise, the following condition in cincinnati.go in MultiArch clusters:

```
if desiredArch == string(configv1.ClusterVersionArchitectureMulti) && currentArch != desiredArch {
    return current, []configv1.Release{current}, nil, nil
}
```

gets evaluated to:

```
if "Multi" == string(configv1.ClusterVersionArchitectureMulti) && "multi" != "Multi" {
    return current, []configv1.Release{current}, nil, nil
}
```

This will cause MultiArch clusters with a set non-empty
`ClusterVersion.Spec.DesiredUpdate.Architecture` field to indefinitely
have available updates set to `[]configv1.Release{current}` because
the `"multi" != "Multi"` logic will always match.
The commit does change the default behaviour of the
`getDesiredArchitecture` method. However, the method is only used once
in the `syncAvailableUpdates` method and nowhere else. The commit adds
the subsequent logic for evaluating a desired architecture to the method
itself and implements the `getCurrentArchitecture` method.

The goal is to introduces "getters" for such values where the
unified capitalization is enforced, and their return values are of the
same nature (e.g., "Multi", "amd64", ...).
