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

 ## API {#api}
 
-### `void ws2812_setleds(rgb_led_t *ledarray, uint16_t number_of_leds)` {#api-ws2812-setleds}
+### `void ws2812_init(void)` {#api-ws2812-init}
 
-Send RGB data to the WS2812 LED chain.
+Initialize the LED driver. This function should be called first.
 
-#### Arguments {#api-ws2812-setleds-arguments}
+---
 
- - `rgb_led_t *ledarray`  
-   A pointer to the LED array.
- - `uint16_t number_of_leds`  
-   The length of the LED array.
+### `void ws2812_set_color(int index, uint8_t red, uint8_t green, uint8_t blue)` {#api-ws2812-set-color}
+
+Set the color of a single LED. This function does not immediately update the LEDs; call `ws2812_flush()` after you are finished.
+
+#### Arguments {#api-ws2812-set-color-arguments}
+
+ - `int index`  
+   The LED index in the WS2812 chain.
+ - `uint8_t red`  
+   The red value to set.
+ - `uint8_t green`  
+   The green value to set.
+ - `uint8_t blue`  
+   The blue value to set.
+
+---
+
+### `void ws812_set_color_all(uint8_t red, uint8_t green, uint8_t blue)` {#api-ws2812-set-color-all}
+
+Set the color of all LEDs.
+
+#### Arguments {#api-ws2812-set-color-all-arguments}
+
+ - `uint8_t red`  
+   The red value to set.
+ - `uint8_t green`  
+   The green value to set.
+ - `uint8_t blue`  
+   The blue value to set.
+
+---
+
+### `void ws2812_flush(void)` {#api-ws2812-flush}
+
+Flush the PWM values to the LED chain.
