Enable the built-in USB serial interface present in some Espressif
MCUs like the ESP32-C3.
This driver uses the peripheral called USB Serial/JTAG Controller
(USB_SERIAL_JTAG), which acts as a CDC-ACM interface towards the
USB host. The USB stack is built into the chip and accessed
by the firmware through a simplified API similar to a "normal"
UART peripheral.
