Simple unions predate flat unions. Having both complicates the QAPI schema language and the QAPI generator. We haven't been using simple unions in new code for a long time, because they are less flexible and somewhat awkward on the wire. To prepare for their removal, convert simple union ImageInfoSpecific to an equivalent flat one. Adds some boilerplate to the schema, which is a bit ugly, but a lot easier to maintain than the simple union feature. Implicit enum ImageInfoSpecificKind becomes explicit. It duplicates part of enum BlockdevDriver. We could reuse BlockdevDriver instead.
