esp32/[ble/wifi]: Update the wireless drivers

This commit updates the Wi-Fi and the BLE driver of ESP32. Most of
the changes rely on using the common sources and header files for
xtensa-based Espressif's SoCs.

The new Wi-Fi driver supports WPA3-SAE for both Station and SoftAP
mode. BLE's coexistence mode was enhanced according to the latest
libraries.

Please note that other sources required minor changes in order to
be compatible with the common sources.
