WS2812 API rework (#24364)
* Begin WS2812 API rework
* Move RGBW conversion, clean up color.h, fix RGBW for AVR bitbang
* Formatting & update PS2AVRGB I2C driver (untested)
* Tested ARM bitbang RGB+RGBW
* Tested ARM SPI RGB - RGBW not working
* Tested ARM PWM RGB+RGBW
* Tested RP2040 PIO driver RGB+RGBW
* Update RGBLight
* Formatting
* Fix BM60HSRGB rev2
* Fix oddforge/vea
* Fix 1k and XD002 RGBLite
* Fix model_m/mschwingen
* Fix handwired/promethium
* Rename `WS2812_LED_TOTAL` for BM60HSRGB
* Fix work_louder boards
* Fix dawn60
* Fix rgbkb/pan
* Fix neson_design/700e and n6
* Fix ergodox_ez/shine
* ergodox_ez/shine: invert indices for left half
* Fix matrix/abelx
* Fix matrix/m20add
* Remove custom rgblight driver for matrix/noah - should be done with lighting layers
* Fix LED indexes for RGBLight split
* Rename `convert_rgb_to_rgbw()` to `ws2812_rgb_to_rgbw()`
* Update WS2812 API docs
* `ergodox_ez/shine`: simplify LED index calculation
* LED/RGB Matrix: Add weak function for LED index resolution
* Bandaid fix for RGB Matrix splits not using WS2812
* `steelseries/prime_plus`: redo custom RGBLight driver
* Update keyboards/steelseries/prime_plus/rgblight_custom.c
