The display list can now refer to canvas ids, but WebContent still had no channel for creating or updating those canvas resources in the Compositor. Both 2D and WebGL canvases would have had to grow the IPC plumbing in the same commit that changes the rendering contexts. This adds the Compositor-side CanvasHost, WebContent transport objects, and the IPC/CMake pieces needed to allocate, update, read back, and destroy remote canvas contexts. The rendering contexts are not switched over yet, keeping this as plumbing for later commits.
