The SHM buffer size might be slightly larger than the expected
size due to 16-byte memory alignment used to create the SHM
buffers.

Frames in shared memory have no specific line alignment
(i.e. stride = width), as opposed to the QVideoFrame, so
the copy need to be done accordingly.

Removes the rendermanager and framewrapper objects along with any
QQuickPaintedItem-based QML render widget classes. This simplifies
the video widget stack implementation.

The new mechanism uses the VideoOutput component of QtMultimedia.
By accessing the VideoOutput's QVideoSink object, we update the
mapped buffer data of a sink's QVideoFrame when new frames are
published. Updates to frames and component sink subscriptions are
managed by a new class called VideoProvider.
