Update types to return the languages for which we tried to run the pro engine

[emjin]

This will make it easier for us to track the impact of new interfile languages (usage, error rate, performance).

• I ran make setup && make to update the generated code after editing a .atd file (TODO: have a CI check)
• I made sure we're still backward compatible with old versions of the CLI.
  For example, the Semgrep backend need to still be able to consume data generated
  by Semgrep 1.17.0.
