QFactoryLoader: continue the port from JSON to CBOR

This continues the effort from the previous commit, by not passing
through the JSON conversion at all, and simply using CBOR directly.

The port in qtbase is complete, but in order to support the conversion
in other modules without introducing breakages, there's a temporary
class used for converting to QPluginParsedMetaData from
QJsonObject. It'll be removed once all other modules have finished
converting.
