Add support for Adafruit Metro M7 (SD and Airlift)

I tried adding the board to PlatformIO myself with some help from the AI. Platform IO was able to recognize the board, however I have no manage to make Zephyr to recognize it.

I think this should work for the most part, yet, I get this error when pio run:

No board named 'adafruit_metro_m7' found.

Please choose one of the following boards:
