...but keep support for deserializing for all older versions in order to play nice with existing .qsb files. The usage of binary JSON and then CBOR is a historical artifact: relying on the QJsonDocument (which we generate for purposes unrelated to binary serialization) was a convenient shortcut. However, writing to and reading from a QDataStream instead (which QShader already does) is trivial. In order not to be limited by potential CBOR requirements in the future, take it all into our own hands. Extend the qshader autotest accordingly.
