pw_protobuf_compiler: Pass plugin paths

- Rather than relying on Python entry point scripts to get paths to
  protoc plugins, pass the paths to the generate_protos.py script. This
  works in environments where the Python entry points are not available.
- Use unique paths for generated proto code in the GN build. This allows
  multiple GN targets to generate code from the same .proto files. The
  CMake build already worked like this.
- Cleanup and reduce code duplication in the CMake and GN proto
  generation code.
- Support Windows builds: generate .bat wrapper script for plugins, fix
  compilation issue that affects some older compilers.
