Implement bind() and recvfrom() for UDP sockets. This is achived by
setting remote field in net_pkt which in return makes recvfrom() fill
in *src_addr. This is only implemented for passiv mode and CIPDINFO needs
to be enabled. Also set net_if to non-dormant when enabling AP mode to
make binding to a port and address possible.

In Passive Receive mode, ESP modem will buffer rx data.
This fix makes the data still available to user,
even though the peer has closed the socket.
Otherwise, user will fail to get the last rx data,
when the socket is closed by the peer.

This driver uses stack buffers to hold AT command strings which are
generated at runtime using sprintk. The buffers are only sized for the
expected range of values, not the full possible range given the datatypes
involved. Values outside this expected range could cause a buffer overflow.
To mitigate this, increase the size of each buffer to hold the full range
of each parameter type.

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.

Claim the net_context mutext associated with a socket before claiming
the socket mutex. The receive callback claims the net_context mutex
internally, which will now always succeed immediately.
The TX path claims the net_context mutex before the socket mutex, and if
we don't use the same order, we can end up in a deadlock.
Fixes#43470.

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).

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.
