drivers: wifi: esp32: fix reconnect issue

Device won't reconnect automatically even if
AP station is available. This fix adds the carrier event, indicating
that network is present again enabling DHCP bound event.
Also, internal wifi event callback was added into wifi
driver to enable proper event handling.

Update west.yml to bring exposed wifi event callback.
