Enable RGB underglow on the CO60 and SteamVan, switch backlight code to QMK built-in code (#7874)

Browse source 
* Add: RGB underglow support using SPI to SteamVan and CO60

* Update: Switch to QMK's baclight implementation for CO60 and SteamVan

* Fix: Remove now unnecessary backlighting code from keyboard files
