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.

The current shield version shows different configuration, including
disabling default ethernet and wifi interfaces. To allow easy
connection from standard headers, this add two new shield designations.
The existing boards overlays and defconfig were updated.
The documentation was update to reflect changes. A new supported
variations section helps to understand what shield variation user need
select to build their own system.
This changes requires changes on esp32 offload tests to reflect new
esp_8266 shield designations. Sam4e_xpro was keeped as the only one
with dedicated overlay and both frdm_k64f and disco_l475_iot1 were
moved to use standard arduino r3 header using extra args.

Add ESP-8266 modules shield. The ESP-01 needs to be loaded with
ESP8266 AT Bin V1.6.2 which is compatible with ESP8266 AT Bin
V1.7.x which is the minimal supported version by ESP WIFI driver.
