gpu: Add handling for (rounded) clip node(s)
This is again mostly a copy of the Vulkan renderer. It's a bit awkward codewise with the new invalidation framework, because we need to cache the previous values individually now, but it's a lot more finegrained, and we don't emit globals multiple times when clips are nested.
