Added QMediaRecorder::status property

QMediaRecorder::state property represents the user request and
changed synchronously during record(), pause() or stop() calls.

Recorder status is changed asynchronously
and represents the actual status of media recorder.

This also makes API more consistent with QMediaPlayer and QCamera.
