monitor: Drop query-qmp-schema 'gen': false hack
QMP commands return their response as a generated QAPI type, which the monitor core converts to JSON via QObject. query-qmp-schema's response is the generated introspection data. This is a QLitObject since commit 7d0f982bfb "qapi: generate a literal qobject for introspection", v2.12). Before, it was a string. Instead of converting QLitObject / string -> QObject -> QAPI type SchemaInfoList -> QObject -> JSON, we take a shortcut: the command is 'gen': false, so it can return the QObject instead of the QAPI type. Slightly simpler and more efficient. The next commit will filter the response for output policy, and this is easier in the SchemaInfoList representation. Drop the shortcut. This replaces the manual command registration by a generated one. The manual registration makes the command available before the machine is built by passing flag QCO_ALLOW_PRECONFIG. To keep it available there, we need need to add 'allow-preconfig': true to its definition in the schema.
