Currently, we have 5 different address type components as A/B test residues. This should be narrowed down to one, removing all the old components.

Ideally, we should also make the address type component more extensible and testable to avoid having 5 different unrelated "tests" in the same campaign.

Acceptance Criteria

• The file app/config/campaigns.yml only contains the test setup for address_type_steps.
• All buckets except direct and multistep_var are removed.
• All component code related to the removed buckets is removed.

Implementation details

• The current file should go into the campaign configuration archive (app/config/archived_campaigns.yml).
• In fundraising-app-frontend the related components need to be removed.
• The components are in the donation form folder.
• They also need to be deleted from the donation address page.
• There probably are no tests for these.
