qmp: Enable a few commands in preconfig state

Commands query-chardev, query-version, query-name, query-uuid,
query-iothreads, query-memdev are informational and do not depend on
the machine being initialized.  Make them available in preconfig
runstate to make the latter a little bit more useful.
The generic qom commands don't depend on the machine being initialized
either; so enabled qom-list, qom-get, qom-set, qom-list-types,
qom-list-properties.
