The current MODULE_WS281X_ATMEGA only supports ATmega core.
This update Kconfig to select MODULE_WS281X_ATMEGA module by
CPU_CORE_AVR_MEGA instead HAS_ARCH_AVR8.

To quickly iterate on animations it is handy to being able to simulate
the output on native.
This adds a VT100 terminal backend to the ws281x driver that outputs
the colors straight to the terminal.
Added driver for the WS2812/SK6812 RGB LEDs often sold as NeoPixels, which due
to their integrated RGB controller can be chained to arbitrary length and
controlled with a single GPIO.
