drivers: wifi: esp32: Add WiFi events for station connect and disconnect

Added events for when the station iface is used to connect and disconnect.
These events will feed the NET_EVENT_WIFI_CONNECT_RESULT and
NET_EVENT_WIFI_DISCONNECT_RESULT events to send information
to applications making use of them
