Added dual antenna for WiFi (based on the ESP32-WROOM-DA module) (#6226)

Browse Source 
* Added dual antenna for WiFi (based on the ESP32-WROOM-DA module)

* Fixed build error

* Fixed indentation and renamed function to setDualAntennaConfig

* Added the RX and TX selection modes as configuration

* Mode code optimization
