qmp: Replace monitor_json_emitter{,raw}() by qmp_{queue,send}_response()

monitor_json_emitter() and monitor_json_emitter_raw() are
unnecessarily general: they can send arbitrary JSON values, even
though we only ever use them for QMP, which may send only JSON
objects.

Specialize the argument from QObject * to QDict *, and rename to
qmp_queue_response(), qmp_send_response().

All callers but one lose an upcast.  The lone exception gains a
downcast; the next commit will get rid of it.
