When "--gpu-render-server path=<path>" is specified, start the render server shipped with virglrenderer and initialize virglrenderer with VIRGLRENDERER_MULTI_PROCESS flag. The flag makes virgl_renderer_context_create_with_flags create proxy contexts instead of venus contexts. Each proxy context requests the render server to fork a subprocess and executes GPU commands in the subprocess.
