[effects] Add a simplified fullscreen blur

If a window is fullscreen and wants fullscreen blur behind it, we
use the blur from logout effect. This is mostly intended for the
Application Dashboard which requires a fullscreen blur. The generic
blur effect is not designed for such usage and is rather costly.

This simplified blur just needs framebuffer blit and midmaps. This
makes it rather cheap in usage and also doesn't need a cached texture.
