Split off QGraphicsView API from KGameRenderer -> KGameGraphicsViewRenderer
Preparing a kdegamegui library by spliting off QWidget things into separate API (see https://invent.kde.org/games/libkdegames/-/tree/work/kossebau/splitlib)
Also rename KGameRenderedObjectItem to KGameRenderedGraphicsObject, given this is a specialized QGraphicsObject, and the name more descriptive IMHO. Having "Graphics" in the name also helps seeing this is related to QGraphicsView.
