AVF: Introduce QCameraCaptureDestinationControl_iid

Can be used like:
QCameraImageCapture->setCaptureDestination(
    QCameraImageCapture::CaptureToBuffer | QCameraImageCapture::CaptureToFile);

Both CaptureToBuffer and CaptureToFile are supported.

If CaptureToBuffer is requested, then it sends imageAvailble signal
If CaptureToFile is requested, it sends imageSaved

imageCaptured is sent only if there is the video frame available.
(e.g. when abstract video surface is used as viewfinder)

Pick-to: 5.15
Fixes: QTBUG-85470
