Doc: Fix multiple documentation issuesv5.5.0-rc1

    - Restore qt3d-index.html as the main landing page. Needed
      for external linking.
    - Fix \inmodule commands for Renderer classes
    - Add proper group so that all three modules are listed on
      the landing page, both C++ and QML modules
    - Remove qt3drenderer-index.html (to be consistent with
      Qt3DCore), copy contents over to the module page and
      to a new file, qt3d-examples.qdoc.
    - Fix indexTitles in qdocconf files, and subprojects for
      Renderer QML types and Qt3D examples

     The Qt3D Renderer module provides an aspect, components, and other supporting types necessary
     to implement 2D and 3D rendering as part of the Qt3D framework.
 
+    To use classes from this module, add this directive into the C++ files:
+
+    \code
+       #include <Qt3DRenderer>
+    \endcode
+
+    To link against the corresponding C++ library, add the following to your qmake project file:
+
+    \badcode
+       QT += 3drenderer
+    \endcode
+
     Classes, types, and functions are declared under the \l [Qt3DCore]{Qt3D} namespace.
