This just adds the boilerplate that goes with the new protocol, without adding any of the actual messages. The protocol is managed by PGPU, and there will be one instance per compositor. The parent side lives on the main thread of the GPU process, and the child side lives on the main thread of the UI process. The protocol is only instantiated if the GPU process is active.
