qapi: Plug trivial documentation holes around former simple unions

The conversion of simple to flat unions left the @data members
undocumented.  Add documentation where it's trivial.  Copy verbatim
from the wrapped type's description where possible.

Leftovers: String (to be taken care of in the next commit), and
TransActionAction (left for another day).
