Move single-consumer lib files into the build module

Moved `entryPoints.ts` and `role.ts` (+ test) from the shared `src/lib/`
directory into `src/modules/build/lib/`, since the build module is their
only consumer. This is part of making CLI modules independent of each
other and of shared code outside the modules.
