Add luatos core esp32c3 ch343

Now with unique CIRCUITPY_CREATION_ID.

This is for the "classic" variant of this board, as described on the vendor's site, that has a CH343 TTL chip tied to the USB port.

What is different from CircuitPython's view from the board version we currently have? Different pinout?

[madcitygeek]

The current board definition doesn't work for me. The difference I found was in the pin definitions for the UART - the existing board uses:

#define CIRCUITPY_ESP_USB_SERIAL_JTAG (1)

While this variant uses:

// Default bus pins
#define DEFAULT_UART_BUS_RX         (&pin_GPIO20)
#define DEFAULT_UART_BUS_TX         (&pin_GPIO21)

// Serial over UART
#define CIRCUITPY_CONSOLE_UART_RX               DEFAULT_UART_BUS_RX
#define CIRCUITPY_CONSOLE_UART_TX               DEFAULT_UART_BUS_TX

Ok, thanks!
