The sync and fence_fd fields on QemuDmaBuf are only used by the GTK display backend for GPU fence synchronization during draw. They are not intrinsic properties of the DMA-BUF itself but transient GL state tied to the display listener. Move fence_fd to VirtualGfxConsole and keep the EGL sync local to the draw operation. Change egl_dmabuf_create_sync() and egl_dmabuf_create_fence() to return values instead of storing them on the dmabuf. This makes the fence lifecycle independent of the dmabuf lifetime.
