fix(panic): fixed cache error being reported as illegal instruction
Closes IDF-6398, IDF-5657, IDF-7015, and IDF-6733
See merge request espressif/esp-idf!27430
On riscv chips accessing cache mapped memory regions over the ibus would
result in an illegal instructions exception triggering faster than the cache
error interrupt/exception.
Added a cache error check in the panic handler, if any cache errors are active
the panic handler will now report a cache error, even if the trigger exception
was a illegal instructions.
Many places in the ESP_SYSTEM are using CONFIG_FREERTOS_UNICORE instead of CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE (GitHub PR)
Closes IDFGH-11333
