wpa_supplicant: Use WPA3 flag to reduce code size

Browse Source 
Flag ESP32_WIFI_ENABLE_WPA3_SAE from Menuconfig is used to
control the stack size required by WPA3. Use the same flag
to compile out the WPA3 code and control the code size.
With this flag disabled code footprint reduces by about 7.7kB
in libwpa_supplicant.a
Update WiFi libs with added checks to cleanly handle disabling
of WPA3 callbacks.

Closes https://github.com/espressif/esp-idf/issues/5971
