Use White channel on RGBW LEDs (#7678)

* Use White channel on RGBW LEDs

Co-authored-by: kwerdenker <sebastian.spindler@gmail.com>

* Manually apply white channel to array

* Move where convert_rgb_to_rgbw is called

* Fix type for rgbw led struct

* Add changes to Ergodox EZ

can revert if deemed necessary

* Revert "Add changes to Ergodox EZ"

This reverts commit aa44db198d40d758ca10470eb94615513592d1dd.

* Revert "Fix type for rgbw led struct"

This reverts commit c5c744cba040201cc0d124400773cf13f8a2cf22.

* Revert "Move where convert_rgb_to_rgbw is called"

This reverts commit cd7f17caf6dd30731c54b3be54490fe4519444f9.

* Revert changes and fix up functions

* Enable white channel for Ergodox EZ as well

* Only run conversion of rgblight is enabled
