esp32: Use the ESP-IDF default esp_console config for ESP32-C3.

The ESP-IDF default on C3 is primary UART0, secondary USB serial/jtag.
Previously MicroPython configured the primary as USB Serial/JTAG and
manually worked with the UART0 console. However UART0 console stopped
working this way in v5.2.2.

The big change is that CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG is no longer set,
as primary console is UART0. However
CONFIG_ESP_CONSOLE_SECONDARY_USB_SERIAL_JTAG is set and IDF provides a
macro CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG_ENABLED which is set if either
primary or secondary esp_console is USB serial/jtag. So need to use that
macro instead.

This work was funded through GitHub Sponsors.
