Enable Spleen in wsfont and modify the font selection logic at runtime

in rasops(9) to allow selecting larger fonts when available.

Summary of the changes:

- Enable spleen8x16 for all architectures, replacing bold8x16_iso1.
- Enable spleen12x24 on all arches but sparc64, replacing gallant12x22.
- Enable spleen16x32 and spleen32x64 on amd64, i386, and arm64 for
  GENERIC kernels.
- Modify the font selection logic in rasops(9) so the 16x32 and 32x64
  fonts are selected if at least 120 columns can be displayed. Screens
  with widths equal or larger than 1920px will use the 16x32 font, and
  screens with widths equal or larger than 3840px the 32x64 one.
