QAspectEngine/QAbstractAspects: get rid of setData

Getting rid of set data and the refactoring on setting the surface implies
that:
- Given the FrameGraph configuration, there may be several RenderViews
  each having a different RenderSurfaceSelector/Window
- This means that the Renderer/QRenderAspect can't know about the surface
  before reading the scene
- This means that the Renderer may be dealing with more than 1 window
- This means that initialization, render and shutdown procedures will have to
  be updated accordingly

Therefore the Renderer was refactored to:
- Be initialized without knowing about a surface
- For each RenderView, check the surface and if different from the previous
  one:
  * Make the context current with it
  * Create the appropriate glHelpers (as Surfaces may have != formats)

TO DO:
- Fix picking
- Fix windows exposition
- Fix shutdown / detection of all windows beging closed
