Introduce Docgen module to extract website data from source code

By adding a compilation `TaskListener` that extracts data from the Bug pattern
and Refaster rule collection (test) classes and writing to JSON output files
in the target directory. This extraction happens as part of the Maven build
using the `docgen` profile.
