Use QAudioOutput in QMediaPlayer

Adjust QMediaPlayer to the new audio output architecture.
One now needs to explicitly add a QAudioOutput to the
media player to get audio playback. While this requires
two more lines of code to set up the media player, it does
make the API consistent between audio and video and also
consistent with what we have in QMediaCaptureSession.

Adjusted auto tests where required and ported all platforms.
