openpgp: Make ComponentAmalgamation return iterator for signatures.

  - Adjust `self_signatures`, `certifications`, `self_revocations` and
    `other_revocations` to return `impl Iterator` over the signatures.

  - Adjust all call-sites including doc tests.

  - Adjust downstream projects (sq, autocrypt).
