esp32/panichandler: Support building against IDFv5.4.2.

DvdGiessen · dpgeorge · commit 431b79146e4c · 2025-07-06T00:14:10.000+10:00
The IDF panic handler resets the watchdog timeout to prevent the printing of the error message from being cut off by a WDT reset. We use the exact same function call in our wrapper function for the same purpose. In IDFv5.4.2 the function used for this was changed from `esp_panic_handler_reconfigure_wdts` to `esp_panic_handler_feed_wdts`, specifically in this commit: espressif/esp-idf@cd887ef Signed-off-by: Daniël van de Giessen <daniel@dvdgiessen.nl>
