If the user copies the BLE example to their own project without understanding the need to enable the BT stack or BTDM BLE settings in the SDK then their build will probably fail at this line due to linker errors.
Closes https://github.com/espressif/esp-idf/pull/6652
Closes IDFGH-4854
Config options have been set such that BLE transport will be the default for ESP32
and SoftAP will be the default for ESP-S2.
CMakeLists.txt for all provisioning examples applicable for ESP32-S2 have also been updated
as these now work fine on ESP32-S2
