LEDs: Add support for the WRGB/RGBW color order (WS2814+ LED chip)

Feature: Add new LED Color Order configs
 >
 Add LED Color Order options with support for the WRGB/RGBW order
 (WS2814 LED chip). Allows for simplified bit OR logic.
 >
 Also replaces LED_TYPE_RGB and LED_TYPE_RGBW with simplified
 LED_TYPE_INTERNAL option. Related logic has been updated to
 follow suit.
