Removed QMediaServiceProvider parameter from media objects constructors.

QMediaServiceProvider should be removed from the public API,
to provide media objects with a custom media service.

A protected QMediaPlayer/QCamera/QRadioTuner/etc constructor
with QMediaService* parameter is a cleaner and more
flexible solution.
