kbd: Add setfont from kbd to set large console font on large displays
Build kbd and ship setfont if enabled with CONFIG_KBD. When CONFIG_KBD is enabled, setconsolefont.sh will double the console font size on large displays (>1600 lines tall as a heuristic). Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm>
