gpu: Use the window event watcher list for Vulkan and D3D12

Events won't be delivered to the regular event watcher list callbacks if a client event filter discards events. Use the special window event watcher list to watch for resizes in the GPU renderers, as events are delivered to this list before a client can potentially discard them.
