Change how esp32c3 build works

Instead of using the custom board use the stock board config with only the
USER_C_MODULES flag pointing back at the microlite module files.

Something has changed and the seperate board directory is not working properly.  Instead use the upstream board config but with
extra modules included in the firmware.
