This will be used when screencasting monitors so that if there's scanout in place, it'll still be possible to blit it to a PipeWire-owned framebuffer, and stream it. Add a new 'blit_to_framebuffer' vfunc to CoglScanout, and implement it in MetaDrmBufferGbm. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1421
