Add video filtering support to VideoOutput
Add the QAbstractVideoFilter base class and integrate it with VideoOutput. This can be used to perform arbitrary filtering or image processing on the frames of a video stream of a VideoOutput element right before the OpenGL texture is provided to the scenegraph by the video node. This opens up the possibility to integrate computer vision frameworks or accelerated image processing with Qt Quick applications that display video streams using Qt Multimedia. Conceptually it is somewhat similar to QVideoProbe, this approach however allows modifying the frame, in real time with tight integration to the scenegraph node, and targets Qt Quick meaning setting up the filter and processing the results of the computations happen completely in QML. [ChangeLog] Added QAbstractVideoFilter that serves as a base class for QML video filtering elements that integrate compute, vision, and image processing frameworks with VideoOutput.
