qemumonitorjsontest: Add a last-resort warning if object-add/device_add are QAPIfied

Browse Source 
When netdev-add was qapified it took us by surprise and we had to
scramble to fix the internals to format conformant monitor arguments.

Add a last-resort early warning system if this happens to object-add or
device_add. Hopefully qemu developers notify us sooner than this.

/**
* testQAPISchemaObjectDeviceAdd:
*
* Purpose of this test is to add a last-resort notification that 'object-add'
* and 'device_add' are not covered by the QMP schema by surprise. Ideally QEMU
* developers will notify us before they switch so we have time to adapt our
* generators first. This didn't work out when netdev-add was converted.
*
* We validate that the QMP schema describes only the expected types and nothing
* else assuming that no new field will be added until final conversion.
