Make it work when using QRhi-on-OpenGL.
Some features like demonstrating a dedicated render thread, or targeting
the window with the Quick content ('onscreen' argument, not clear why
that was added in the first place), are now removed. Some of these could
be reintroduced in future examples, not necessarily in combination with
OpenGL. For now they are removed since the cost of porting and
maintaining all that is not reasonable at this point.

...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.
