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.
