Workaround for EEVEE ThicknessFromShadow shader.

EEVEE light evaluation uses layered sub-pass tracking. Currently, the tracking supports transitioning a layer to a different layout once per rendering scope. When using the thickness from shadow, the layers need to be transitioned twice: once to image load/store for the thickness from shadow shader and then to a sampler for the light evaluation shader. We work around this limitation by suspending the rendering.

The reason we need to suspend the rendering is that Vulkan, by default, doesn't support layout transitions between the begin and end of rendering. By suspending the render, the graph will create a new node group that allows the necessary image layout transition.

This limitation could also be addressed in the render graph scheduler, but that would be quite a hassle to track and might not be worth the effort.
