Silhouette Overlap Overlay

Added Object Overlap Overlay

 - Added R32UI support to GPU_framebuffer
 - Added R32U support to draw manager
 - The overlay mode has a object data pass that will render 'needed' data to specific buffers so we can mix them together via a deferred rendering. In future will also add UV's and other data
 - Overlap is implemented as an overlay so it could be used on top of the Scene lighted Solid mode (that will be rendered by Eevee.
