This is work towards snapshotting the remote iframes bug 282664. With site isolation, snapshotting has to happen in a central process such that no WebContent process is allowed to see the drawing of another WebContent process. Since all the WebContent processes share the same GPUProcess for UI side compositing, the GPUProcess can be used for the "snapshot compositing" as well.
