This is solving a papercut, where the C++ build was relying on the local dbscheme file to be up-to-date, even if all the information for building is actually in `schema.yml`. This made a pure C++ development cycle with changes to `schema.yml` clumsy, as it required a further dbscheme generation step. Now for C++ the dbscheme is generated internally in the build files, and thus a change in `schema.yml` is reflected immediately in the C++ build. A `swift/codegen` step for checked in generated code (including the dbscheme) is still required, but a developer can do it just before running QL tests or committing, instead of during each C++ recompilation. Some directory reorganization was also carried out, moving specific generator modules to a new `generators` python package, and only leaving the two drivers at the top level.
