Ricardo Pardini 622ef30f3c adapt obtain_complete_artifact() and friends to new reversioned scheme; introduce UPLOAD_TO_OCI_ONLY=yes for deploying to remote cache
> tl-dr: only deploys to remote OCI if `UPLOAD_TO_OCI_ONLY=yes`; stop leaving junk behind in local cache in many situations

- simplify CLI artifact building parameters and behaviour
    - `ARTIFACT_USE_CACHE` is now deprecated, and its behaviour is the default
    - for _any_ uploading to OCI to occur, `UPLOAD_TO_OCI_ONLY=yes` **must** be present; in this case, reversioning is not done
    - `FORCE_ARTIFACTS_DOWNLOAD` is completely removed (use `download-artifact` instead)
    - `cli_obtain_complete_artifact()`'s and `build_artifact_for_image()`'s reversioning is now moved to common `obtain_complete_artifact()`
- `standard_artifact_reversion_for_deployment()`:
    - check for hashed deb existence only if reversioned does not exist
    - touch the reversioned file if it already exists; helps to clean up junk later
    - delete hashed version after reversioning, so we don't leave trash behind
        - unless in `download-artifact` mode, which `touch`es the hashed version
        - we can later delete old files from packages-hashed to keep junk under control
- refactor `obtain_complete_artifact()`
    - extract function `artifact_dump_json_info()` since obtain is large enough already
    - when deploying to remote, always ignore all local and remote caches
    - introduce `artifact_is_available_in_revisioned_local_cache()`
        - if not deploying to remote, and revisioned cache exists, use it directly
        - if deploying to remote, reversioned is not checked and not created
    - if deploying to remote, force `DEB_COMPRESS=xz`
    - if deploying to remote, completely remove the local cache base dir after upload is done (no more junk leftover)
