If esp_restart_noos() is run and the stack address points to external memory (SPIRAM) then Cache_Read_Disable() raises up the error "Cache disabled but cached memory region accessed" to fix this we switch stack to internal RAM before disable cache. Added unit tests. Closes: https://github.com/espressif/esp-idf/issues/5107
