Fix Q_FLAGS deprecation warning

A Q_FLAGS macro has managed to get in with the QML render pass API and
now triggering warnings, which fails if building with warnings are
errors. Macro replaced with the recommended Q_FLAG macro.

Fix crash at exit with renderMode Inline

A View3D with renderMode: View3D.Inline allocate a QQuick3DSGRenderNode
and stores it as m_renderNode. On scene-graph teardown
cleanupNodesOnShutdown() deletes that node which leads to the
invalidateSceneGraph() slot to be called. In invalidateSceneGraph() only
m_node (the Offscreen FBO node) was cleared, so m_renderNode is left
dangling. When the render thread then emits invalidated it ends up in
onReleaseCachedResources which queries the renderer, which for Inline is
now a stale pointer. Note that Offscreen never hit this because
invalidateSceneGraph() cleared m_node.
