Those types are special, as they are the base of all other QOM types. In
next commit, we'll introduce an extra step in module initialization for
target-info-* types.

However, those types depend on TYPE_OBJECT, which is only registered
at MODULE_INIT_QOM step.

To avoid having to introduce another step, and modify all code calling
module_call_init(MODULE_INIT_QOM), we simply register those base types
directly in the static constructor, before anything else.
