Move Ergodox EZ RGB Light code to custom driver (#7309)

Browse source 
* Move Ergodox EZ RGB code to custom driver

Also implements full addressing of Ergodox EZ's LED Strip, as written by seebs
Co-authored-by: Seebs <seebs@seebs.net>

* Make Clipping range accessible for custom drivers

* Remove RGBW_BB_TWI from driver and docs

* Revert changes to clipping range support

* Use just rgblight_set instead of full custom driver

* Convert to i2c_master commands

* Rename rgblight driver and clean up includes
