2025-05-22kernel: Optimize console & loggingQuinn Stephens
* Modified draw loops to use `fbdev_get_index()` less often. * Created `cons_fast_putch()`, then used it to implement `cons_putch()` and `cons_putstr()`. This way, when printing an entire string, the lock acquire/release and cursor hide/show will only happen once, instead of once per character. * Modified `syslog_write()` to use `cons_putstr()`.
