Add QQuickContentItem to produce more useful debug output

With the following code:

    ApplicationWindow {
        Component.onCompleted: print(contentItem)
    }

Before:

    QQuickItem(0x16043e52600)

After:

    QQuickContentItem(0x28a89b96440, "ApplicationWindow")

QQuickWindow has a similar concept (QQuickRootItem).
