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 Co-authored-by: Dasky <32983009+daskygit@users.noreply.github.com> --------- Co-authored-by: Dasky <32983009+daskygit@users.noreply.github.com>
