libcamera: yaml_parser: Move Size handling to geometry.cpp

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.
