[ESP32] Support for ESP32C2 and changes to not initialized BLE for al…

…ready provisioned nodes (#22967)

* [ESP32]: Remove device name from the ble log as we do not add that in
the advertising packet

* Remove the sdkconfig.old

* [ESP32]: Platform, doc, example change to support ESP32C2

* [ESP32]: Do not initialize BLE if wifi/thread is already provisioned.

If ble is only used for commissioning then there is no use to initialize
the ble.
Also, renamed the config option for the purpose to make it more aligned.

* Restyled by clang-format
