Previously, a default value for ESP_WIFI_PASS was intentionally defined only if DOXYGEN was also defined, to allow ESP_WIFI_PASS to be left undefined for using APs without authentication. With PR #17415 the definition was changed to always define a default value for EPS_WIFI_PASS. This made it impossible to use APs without authentication. The commit reverts this change.
The semantics of defining an SSID prefix that overrides the already defined SSID exactly when and only when it is set, and then enabling dynamic SSID generation with that prefix, made handling the parameter definition unnecessarily difficult and hard to understand.
Defining a boolean option that enables dynamic SSID generation, which then simply reuses the defined SSID as a prefix, makes it much more understandable and easier to handle, especially with respect to Kconfig.
This is an implementation of the ESP32 SoftAP mode using the
`esp_wifi_ap` pseudomodule.

Due to stability reasons, the SoftAP interface of the WiFi module was always enabled in former versions even if only the station interface was used. Therefore the WiFi modem had to be always active and the SoC could not enter the modem sleep mode. Therefore, the SoftAP interface is only enabled when ESP-NOW is used.
The WiFi interface should be stopped before reboot or sleep. But stopping the WiFi interface disconnects an existing connection. Usually, esp_wifi_netdev tries to reconnect on an disconnect event. However, trying reconnect with a stopped WiFi interface may lead to a crash. Therefore, the stop event has to be handled.
