log and lint addon id and version from xpi SignFile

[g-k]

Follow up items from comments and original issue:

• return parsed ID and version to SignFile in xpi
  • log parsed ID and version with the "signing operation succeeded" lines instead of from the repacking code
  • when signing in mode ModeAddOn and ModeAddOnWithRecommendation check the lints:
    • warn for a missing manifest.json file
    • warn for multiple IDs: applications.gecko.id and browser_specific_settings.gecko.id
    • warn for manifest ID not matching request Options.ID
    • warn for a missing version

Warnings return errors if we want to do more linting in autograph and other web extension signers pass for legitimate uses.
