console: Add config EARLY_OVERRIDE_LOGLEVEL for overriding early log level
For early boot stages before POSTCAR it can override log level by get_option(), default set to n. Make init_log_level() set log level for all stages because get_log_level() is called by printk so avoid calling an overridden function in case it impacts performance.
Tested=On OCP Delta Lake, log level can be overridden by get_option().

This change isn't what I expected from CB:45134. I was expecting to remove the multiple checks for CONSOLE_LEVEL_CONST. This clean-up isn't needed for CB:45134, so it can be moved after it.
https://review.coreboot.org/c/coreboot/+/45684/1/src/console/init.c File src/console/init.c:
https://review.coreboot.org/c/coreboot/+/45684/1/src/console/init.c@21 PS1, Line 21: EARLY_OVERRIDE_LOGLEVEL This config isn't defined until CB:45134 and generally, I don't think the check is needed in this file.
