Before clearing the screen, ensure that no previous output of firmware or UEFI programs will be overwritten on serial devices or other streaming consoles. This helps generating complete boot logs. Tested regarding multi-output against qemu-x86_defconfig. Still, there were remaining concerns about side effects, so this is provided as an opt-in feature.
