CMake build: Change how third party libraries are included

- Always use dir_pw_third_party_nanopb as a path.
- Improve error messages when building Nanopb protos without
  dir_pw_third_party_nanopb set.
- Specify python3 instead of python in case the build isn't run in a
  Python 3 virtual environment.
