qapi: Allow introspecting fix for savevm's cooperation with blockdev
'savevm' was buggy as it considered all monitor-owned block device nodes for snapshot. With the introduction of -blockdev, the common usage made all nodes including protocol and backing file nodes be monitor-owned and thus considered for snapshot. This is a problem since the 'file' protocol nodes can't have internal snapshots and it does not make sense to take snapshot of nodes representing backing files. This was fixed by commit 05f4aced658a02b02. Clients need to be able to detect whether this fix is present. Since savevm does not have an QMP alternative, add the feature for the 'human-monitor-command' backdoor which is used to call this command in modern use.
