(Re)Fixing K-type RGB lighting (#12084)

* initial rgb driver fix

* added underglow LEDs and fixed typo in RGB locations

* removed test code

* added my key maps

* updated rgb keymap to work with changes

* refactored my code to make it more maintainable and updated keymaps.

* added GPL licence

* Turned off matrix scan rate debug info

* added checks if RGB matrix is enabled to fix errors when building keymaps without RGB matrix enabled

* Apply suggestions from code review by fauxpark

Co-authored-by: Ryan <fauxpark@gmail.com>

* Renamed led driver file to be less ambiguous

* Renamed is31fl3733 driver files to is31fl3733-dual
