Zbigniew Jędrzejewski-Szmek ce04f8a331 updatectl: fix feature JSON parsing (#43617)
## Summary

`updatectl features` failed because it expected the old feature JSON
fields,
while `systemd-sysupdate` now returns `id`, `isEnabled`, and
`documentation`
as an array.

This change:

- Aligns `updatectl` with the current feature JSON schema.
- Unifies JSON output between `systemd-sysupdate`, D-Bus, and Varlink.
- Adds support for multiple `Documentation=` entries for Features and
  Components.
- Exposes and parses `appstream` and `suggested` metadata.
- Propagates condition-evaluation errors through `condition_test_list()`
and
  `feature_is_suggested()`.
- Reports suggestion-evaluation failures instead of silently treating
them as
  `false`.
- Improves JSON dump error handling.
- Expands `TEST-72-SYSUPDATE` coverage and fixes its unknown-field
assertion.
- Documents the `DescribeFeature()` JSON field transition in `NEWS`.
- Keeps the existing Component name list for `sysupdated` compatibility.

The `name`/`enabled` to `id`/`isEnabled` transition is intentional and
documented as a v262 payload change.

Fixes #43603
