Fixes #9749.
The MicroPython folks discovered this ESP-IDF bug: espressif/esp-idf#14456, which can be worked around by doing
CONFIG_ESP_SYSTEM_HW_STACK_GUARD=non both ESP32-C3 and ESP32-C6. Seeespressif/esp-idf#14456

I saw this initially and kept in mind. It sounded similar to #9749: a crash after a few minutes on C3 when using wifi.
I tested on a C3. With this fix the test program in #9749 ran for hours before I manually stopped it. Without it, it usually got a hard fault within a few minutes.
