This patch removes more main thread dependencies from the content side of WebGPU. Instead of issuing a resource update for an external image, we now use an async image pipeline in conjunction with CompositableInProcessManager from part 1. This allows us to update the HTMLCanvasElement bound to the WebGPU device without having to go through the main thread, or even the content process after the swap chain update / readback has been requested.
