Add optional flags and rect to QSGRenderNode
Having rendernodes triggering fullscreen updates with the software backend
is not ideal. Therefore, introduce the option of reporting that the rendernode
is well-behaving, meaning it only writes inside the reported bounding rectangle.
Similarly, the OpenGL batch renderer can keep using the depth buffer when the
rendernode is known to behave like the renderer expects.
