qapi/qom: Add ObjectOptions for cryptodev-*

This adds a QAPI schema for the properties of the cryptodev-* objects.

These interfaces have some questionable aspects (cryptodev-backend is
really an abstract base class without function, and the queues option
only makes sense for cryptodev-vhost-user), but as the goal is to
represent the existing interface in QAPI, leave these things in place.
