Add ATMegaZero ESP32-S2 microcontroller (#5569)

## Summary
Adds support for the new ATMegaZero ESP32-S2 board. Adds the relevant section to `boards.txt` and adds the folder for the `atmegazero-esp32s2` with the proper `pins_arduino.h` to the `variants` folder.

## Impact
Allows users to compile code properly for the ATMegaZero ESP32-S2 without having to use a similar board and manually entering pin numbers.
