feat(cmake): add native file dialog support for Windows/Linux

- Introduced a new file dialog implementation using nativefiledialog-extended for better file handling on Windows and Linux platforms.
- Updated CMake configuration to link the new file dialog library and include necessary directories.
- Enhanced the editor library to conditionally link a test support library when testing is enabled.

Benefits:
- Improved user experience with native file dialogs for file operations.
- Streamlined testing support in the editor library, enhancing modularity and maintainability.
