qapi: Convert simple union TpmTypeOptions to flat one
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 TpmTypeOptions to
an equivalent flat one, with existing enum TpmType replacing implicit
enum TpmTypeOptionsKind. Adds some boilerplate to the schema, which
is a bit ugly, but a lot easier to maintain than the simple union
feature.
