Move SceneXRender into a plugin Summary: First step for loading the compositor Scenes through plugins. The general idea is that we currently needlessly pull in all the Scenes although only one will be used. E.g. on X11 we pull in QPainter, although they are not compatible. On Wayland we pull in XRender although they are not compatible. Furthermore our current Scene creation strategy is not really fault tolerant and can create situations where we don't get a compositor. E.g on fbdev backend the default settings won't work as it does not support OpenGL. Long term I want to tackle those conceptional problems together: we try to load all plugins supported by the current platform till we have a scene which works. Thus on Wayland we don't end up in a situation where we don't have a working compositor because the configuration is bad. To make this possible the switch statement in the Scene needs to go and needs to be replaced by a for loop iterating over all the available scenes on the platform. If we go there it makes sense to replace it directly with a plugin based approach. So this is a change which tackles the problem by first introducing the plugin loading. The xrender based scene (as it's the most simple one) is moved into a plugin. It is first tried to find a scene plugin and only if there is none the existing code is used.
