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
