USB DTE support

For USB enabled targets (ESP32-S2 and ESP32-S3), it is possible to connect to the modem device via USB.

1. In menuconfig, navigate to Example Configuration->Type of serial connection to the modem and choose USB.
2. Connect the modem USB signals to pin 19 (DATA-) and 20 (DATA+) on your ESP chip.

This example supports USB modem hot-plugging and reconnection.
