feat(bt): Add initial support of Bluetooth Classic on ESP32-S31

Browse Source 
- feat(soc_caps): Enable BT Classic and BLE in esp32s31
- Add git submodule for ESP32-S31 bt controller lib files
- changed sdkconfig.defaults and README for Bluetooth Classic examples
- change(docs): Added vendor HCI documentations for ESP32-S31
- change(Bluedroid): Adapt to ESP32-S31 due to some API differences on
  Bluetooth controller from ESP32
- change(bt): Modify CMakeLists.txt to support the Bluetooth dual-mode
  architecture on ESP32-S31
- change(bt): Add ECC P-192 functions to tinycrypt
