Use shared/lib in build embeddings tool and run this tool as a module (…

…#4254)

This makes it possible to use shared libraries (more to come) and common
config processing in NL server.

With this, more GCS download functions could be removed.

Also remove autogen input support since no autogen descriptions exist
anymore.
