[eas-cli] integrated credentials service with android submissions

[quinlanj]

Checklist

• I've added an entry to CHANGELOG.md if necessary.
• I've tagged the changelog entry with [EAS BUILD API] if it's a part of a breaking change to EAS Build API (only possible when updating @expo/eas-build-job package).

Why

This PR integrates the credentials service into the Android submission workflow. Notable changes:

• If the user passes in the path argument when they run submissions, we use that and fall back to a prompt if there the path they passed was invalid. No credentials are saved on www in this case.
• If there is no path argument when submissions is run, we use the credentials service.

Test Plan

• manually test important cases
• new tests pass
