993cad1b4a wifi: esp_at: cleanup sockets at network close
Some sockets (UDP sockets at least) do not generate "<N>,CLOSED"
messages when the WiFi network drops. As a result the networking stack
thinks these sockets are still open after the network has dropped, and
after any subsequent reconnections.

This affects the DNS resolver library in particular, which leaves UDP
sockets open permanently by default.

Manually close these sockets when the network drops to ensure a clean
state the next time the network connects.

fb60aab245 drivers: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

840bcd802d wifi: esp_at: disable CWMODE auto connect
In the newer ESP32 AT command versions, the CWMODE command takes an
optional parameter (<auto_connect>) which controls whether the module
will automatically attempt to connect to an AP when switching modes.

This parameter defaults to enabling auto-connect if not specified.

Without this change, modules can successfully connect to an AP before
the `CWAUTOCONN=0` command is processed, resulting in a
`NET_EVENT_WIFI_CONNECT_RESULT` before `NET_EVENT_IF_UP`.

eb78d70805 drivers: wifi: esp: stop using pkt->work in TX path
Usage of k_work object from within net_pkt results in undefined behavior
in case when net_pkt is deallocated (by net_pkt_unref()) before work has
been finished.

Use per socket k_work object (sock->send_work) to submit send work and
put net_pkt objects onto k_fifo (sock->tx_fifo). Add a helper function
esp_socket_queue_tx() for that, which will make sure that packets are
enqueued only when send work handler will be successfully submitted (so
that all packets are consumed/dereferenced).

b4854debd1 drivers: wifi: esp_at: rename driver from esp
Recently WiFi ESP32 driver (utilizing WiFi radio in ESP32 SoC) was
introduced into drivers/wifi/esp32/ and it already caused confusion as
there was existing drivers/wifi/esp/ directory for ESP-AT
driver (utilizing external WiFi chip, by communicating using AT commands
from any serial capable platform). So question has arisen whether it is
good to merge both, while they are totally different drivers.

Rename ESP-AT driver to be placed in drivers/wifi/esp_at/, so that it is
easier to figure out difference between "esp32" and "esp_at" just by
looking at driver name. Rename also DT compatible and all Kconfig
options for the same reason.
