Implement global configuration for PDF and FFmpeg in converters

Browse source 
- Added global configuration support for PDF and FFmpeg in the Knowledge Base, allowing converters to utilize default settings.
- Introduced functions to set and get global configurations for PDF and FFmpeg, enhancing flexibility in converter options.
- Updated OCR and Video converters to leverage global settings, with tests ensuring proper functionality and overrides.
- Enhanced test cases to validate the use of global configurations and property overrides, improving test coverage and reliability.
