bitmap: Remove the split between 'image library' and 'fallback'
Previously the bitmap code was setup so that there could be an image library used to convert between formats and then some 'fallback' code when the image library can't handle the conversion. However there was never any implementation of the conversion in the image library so the fallback was always used. I don't think this split really makes sense so this patch renames cogl-bitmap-fallback to cogl-bitmap-conversion and removes the stub conversion functions in the image library.
