Instead of always swapping buffers and flipping the back buffer, make it possible to scan out a provided buffer directly without swapping any EGL buffers. A buffer is passed as an object implementing the empty CoglScanout interface. It is only possible to do this in the native backend; and the interface is implemented by MetaDrmBufferGbm. When directly scanned out, instead of calling gbm_surface_lock_front_buffer() to get the gbm_bo and fbid, get it directly from the MetaDrmBufferGbm, and use that to create the page flip KMS update. https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
