New board def for ESP32C3 generic luatos

**Describe the problem you have/What new integration you would like**

New board defs for ESP32C3 were included in a recent release. None are pin compatible with a readily available and economically priced C3 board to the point the reserved pins of the existing C3 definitions prevent compilation due to pins thought to be flash q-lanes but actually control the onboard leds (GPIO12 & GPIO13) on this particular board layout.

The board datasheet is here:

**Please describe your use case for this integration and alternatives you've tried:**

Want to be able to build for this board without hacky workarounds to make esphome think it is flashing a different variant. Currently flashing a vanilla image over USB, then calling the variant an S2 board lets me assign to the desired pins and then can be updated OTA.

**Additional context**

The Board is DIO, typical QIO pins are not used for flash.
