kernel: replace Spleen font with an enlarged version of the original KDL font

Recently we introduced Spleen as a larger font for KDL for high
resolution displays. However, it looks quite different from our original
font. I designed an enlarged version of our original font (designed by
Brian J. Swetland and also found in NewOS, LK and Fuchsia) to use
instead.
