Introducing config option `CONFIG_ESP_NETIF_SET_DNS_PER_DEFAULT_NETIF` to overcome LWIP limitation of using global DNS server info. This config option enables LWIP callbacks to collect per netif DNS server info and then restores global DNS servers of whichever network interface is selected as default. LWIP submodule update v5.2: git log --oneline f1746813..3a3d1fb3 - dns: Allow storing dnsserver per netif (espressif/esp-lwip@3a3d1fb3) - api_msg: Fix unused local variable if LWIP_NETCONN_SEM_PER_THREAD=1 (espressif/esp-lwip@aa4f6e78) - lwip: fix gcc -fanalyzer warnings (espressif/esp-lwip@4297782b)
