QInputDevice: Parent default keyboard to core app singleton

With this we can avoid leaking the QInputDevice which is created when
the platform plugin does not provide any. The onwership is solved in a
similar way as in the plugins, except that here we have no parent which
really fits, so we use QCoreApplication::instance instead.

Pick-to: 6.0
