Add a support for selecting the output device used by QSoundEffect

The QSoundEffect can be forced to use a specific audio output device.
This is useful on a system with multiple output devices as individual
QSoundeffects can use separate output devices.
Due to way QAudioOutput (alternate implementation behind QSoundEffect)
is implemented, QAudioDeviceInfo is used as a method of defining
the output device to be used.
