… collations (#11629)

This PR enhances the observability of our logs when validators refuse to
fetch advertised collations for certain para IDs.

The validator keeps track of advertised collations from collators.
Then, the validator checks if it has sufficient slots
(`is_slot_available`) and if the collation can be seconded
(`can_second`).
If either of the mentioned functions fails, the validator silently
ignores the collation.

This PR aims to surface this behavior and help investigate further
issues.

This PR is already deployed on validators and has surfaced:
- #11625

Part of:
- #11377

This pull request is amending an existing release. Please proceed with extreme caution,
as to not impact downstream teams that rely on the stability of it. Some things to consider:

  • Backports are only for 'patch' or 'minor' changes. No 'major' or other breaking change.
  • Should be a legit fix for some bug, not adding tons of new features.
  • Must either be already audited or not need an audit.
Emergency Bypass

If you really need to bypass this check: add validate: false to each crate
in the Prdoc where a breaking change is introduced. This will release a new major
version of that crate and all its reverse dependencies and basically break the release.
