libcamera: yaml_parser: Return nullopt on error
The YamlParser::getList<>() function returns an std::optional<> to allow callers to identify cases where parsing the .yaml file failed from cases where the parsed list is just empty. The current implementation returns a default constructed std::optional in case of errors with return {}; The returned value is thus equal to std::nullopt, but the code can be easily misinterpreted as returning an empty vector by a reader.
