Add parent-child relationship on audio sources and sinks

QAudioSink and QAudioSource must propagate their parents to
the platform specific implementation to enable correct operation
of the moveToThread function. Furthermore, all QObject elements
that are owned by audio sink/source must also establish
the parent-child relationship. This mainly affects QTimer's used
by the audio sink/sources.

Fixes: QTBUG-108187
