qom: Improve {qom,device}-list-properties error messages

device-list-properties reports

    Parameter 'typename' expects device

when @typename exists, but isn't a TYPE_DEVICE.  Improve this to

    Parameter 'typename' expects a non-abstract device type

qom-list-properties reports

    Parameter 'typename' expects object

when @typename exists, but isn't a TYPE_OBJECT.  Improve this to

    Parameter 'typename' expects a QOM type
