Un-extern RGBLight led[] array

[fauxpark]

Description

Keyboard and keymap code should use the existing RGBLight API to manipulate the LEDs instead of directly modifying the array.

I expect CI to reveal a bunch of issues here as there are still some boards which are doing so.

hineybush/hbcp:hiney is failing due to use of the removed content.

Keymap itself doesnt seem to add a whole lot of value. My preference is just to remove it as a "user" keymap.
