Fix dependency tree so that lwip doesn't depend on any specific network
interface component.
Network interface drivers shall depend on esp_netif.
esp_netif shall depend on lwip (but not on any specific interface
driver) -- it optionally depends on vfs and esp_eth (need ethernet
header for L2/bridge mode)
Prior to this change "esp_wifi_clear_default_wifi_driver_and_handlers"
will not remove netif pointer from table when both AP and STA interfaces were
created and destroying default wifi interfaces is done in unfortunate
order. As a result there is dangling pointer left and it may cause crash in
later code (i.e. when esp_wifi_stop() is called).
