backlight: add minimal tool to save/restore screen brightness across reboots
As many laptops don't save/restore screen brightness across reboots, let's do this in systemd with a minimal tool, that restores the brightness as early as possible, and saves it as late as possible. This will cover consoles and graphical logins, but graphical desktops should do their own per-user stuff probably. This only touches firmware brightness controls for now.
