Implement save file dialog functionality across platforms

- Added ShowSaveFileDialog and its platform-specific implementations for Windows and macOS, allowing users to save files with specified names and extensions.
- Enhanced the FileDialogWrapper class to support both native and bespoke dialog options based on feature flags.
- Updated the editor manager to utilize the new save dialog for ROM and project file saving, improving user experience and file management.
- Refactored existing dialog methods to ensure consistency and maintainability across different platforms.
