Sign artifacts after compilation

If compilation succeeds, pass over all the artifacts we generated and
produce an OdsignInfo file with all the names and digests and a
signature of it using the CompOS key.

Various refactorings along the way to make it eaiser:
- Extract the odrefresh ExitCode enum for reuse
- Extracted a Signer, distinct from an ArtifactSigner
- Defined OdrefreshContext to stop the linter complaining about a
  function with >7 arguments.

Also added more debugging to help fix my various silly mistakes.

Bug: 161471326
Test: composd_cmd forced-odrefresh -> signature file produced
