Move legacy rendercontrol example into a subdirectory
...called rendercontrol_opengl under examples/quick/rendercontrol. This
example is going to be migrated to support operating with RHI-on-OpenGL
later on.
Additionally, we can this way introduce more rendercontrol examples in
the future, for example to show how to do things with Vulkan, Metal,
D3D.
