Support for Adafruit ESP32-S2 TFT Feather (#4912)

Browse Source 
Support for optional PowerSupply component for ST7789V

This commit makes the power supply required if the model configured in the ST7789V component is set to ADAFRUIT_S2_TFT_FEATHER_240X135. There are at least two boards from Adafruit with this configuration but with a different pin out.

This also adds the board pins definition for the board I have. There is discussion on the forums about the other board's documentation not matching reality and I don't have a physical board to confirm.
