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.

Framebuffer console: Add spleen font (12x24)

Use this larger font when the screen resolution is large (more than
1920x1080 in both directions). The usual font is too small and not easy
to read on such high resolution displays.

Reuse two unused lower ASCII chars for block drawing.

Characters 17, 18 and 19 (device control 1, 2 and 3) become "full block",
"upper filled block" and "lower filled block". Using back- and foreground
color inversion these could be reduced to a single "half block", but
having them available as idividual chars is more convenient.

Renamed system/core to system/kernel.
