feat: [editor] Add encoding detection and conversion support

Add encoding detection and conversion functionality to the editor, including:

- Integrate chardet/uchardet/icu libraries for encoding detection
- Add GB18030-2022 encoding support with special character handling
- Implement encoding conversion between different character sets
- Add encoding selection UI in status bar
- Support reload file with different encodings
- Add encoding configuration file with supported encoding list

The changes improve text file handling by:
- Automatically detecting file encodings on open
- Supporting manual encoding selection via UI
- Preserving encoding when saving files
- Handling special cases for Chinese encodings
- Providing better user feedback about current encoding
