swscale: split out RGB48 output functions from yuv2packed[12X]_c().

Browse Source 
This is part of the Great Evil Plan to simplify swscale. Note that
you'll see some code duplication between the output functions for
different RGB variants, and even between packed-YUV and RGB
variants. This is intentional because it improves readability.
