OAPI: integrate Python code generator in Makefile

Instead of having the Python code generator as a separate shell script,
include it in the Makefile. There are now three make targets:

- generate-go: only generate Go code, for the Worker & Manager
- generate-py: only generate Python code, for the Blender add-on
- generate: run both
