The YamlObject::Accessor structure is designed to extend the YamlObject class with new getter and setter types without modifying yaml_parser.cpp. This feature is used for various libcamera classes, while standard C++ types are handled in yaml_parser.cpp. The Size class is an outlier: it is a libcamera class, but is handled in yaml_parser.cpp. Move it to geometry.cpp. Drop the std::vector<Size> specialization as it is currently unused.
