[Keyboard] Small Refactor of Duck boards (#5521)

* first [ass at pulling out common duck library functions

* use new library in jetfire

* use new library in duck lightsaver

* use new library in octagon v2

* put Device into the library

* refactor send_value

* refactor send_value and send_color

* use pragma once

* use pragma once

* use pragma once

* use pragma once

* rename backlight_led to indicator_leds to match with other duck boards

* rename enum

* make #define names consistent

* rename ducklib to duck_led

* update rules.mk ?= to =

* put rgb in the correct order

* add debounce debugging printouts

* turn on bootmagic lite and set it to the top left most key commonly programmed as Escape

* add reset key documentation

* fix that typo

* Update keyboards/duck/duck_led/duck_led.c
