refactor: use localizations for menubar and structure optimization

- use localizations for menubar
- bump AutoGGUF version to v2.0.0
- rename imports_and_globals.py to globals.py
- reformat code
- use file select for Merge/Split GGUF functions
- move general functions verify_gguf and process_args to globals.py
- create Plugins class for extensibility
