Breaking changes for preview features

• When inject-files outputs to COSI, the non-verity filesystems will be shrunk.
• The output artifacts behavior and the inject-files config API has changed:
• unsignedSource has been removed from inject-files.yaml. Instead, the unsigned and signed file paths are now the same.
• Unsigned files are now placed in // (previously /).
• For example: ./artifacts/ukis/vmlinuz-6.6.96.2-2.azl3.efi instead of ./artifacts/vmlinuz-6.6.96.2-2.azl3.efi.
• A new type field has been added to inject-files.yaml.
