qapi: add a dictionary form for TYPE

Wherever a struct/union/alternate/command/event member with NAME: TYPE
form is accepted, desugar it to a NAME: { 'type': TYPE } form.

This will allow to add new member details, such as 'if' in the
following patch to introduce conditionals, or 'default' for default
values etc.
