Introduce BugPatternTestExtractor for documentation generation (#494)
This new `Extractor` implementation collects identification and replacement source code from `BugChecker` unit tests. While there: - Refactor the existing `Extractor` setup such that instances are service-loaded and need to implement only a single method, thereby avoiding the need to align logic between multiple source code locations. - Extend the validation performed by the `Compilation` test helper class. - Extend the `ErrorProneTestHelperSourceFormat` check to support source code passed to the `Compilation` test helper class.
