Previous changes have applied mechanical refactorings, but this change
hand-migrates the remaining logic which was too complex to identify.
This change should have no behavior change; famous last words.

Exempt-From-Owner-Approval: trivial refactoring

Since we have over 100 unique schemas across the OS, it would be
incredibly tedious to try migrating all that logic to use the more
efficient TypedXmlSerializer and TypedXmlPullParser interfaces.
To aid this migration process, this change adds Refaster templates
that offer to refactor matching existing code in a no-op fashion.
This change also upgrades Error Prone to the latest release.
