qapi: Drop simple unions 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. The previous commits eliminated simple union from the tree. Now drop them from the QAPI schema language entirely, and update mentions of "flat union" to just "union".
