Georges Basile Stavracas Neto 21a21e7f68 cogl/scanout: Allow blitting to framebuffer
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.
