Help with support for ESP32-S3 Dev Module

Okay then very miracously the Arduino-ESP32 board definition is wrong. It clearly defines the native USB-CDC of the ESP32S3 as the standard Serial

          waveshare_esp32s3_touch_lcd_128.build.usb_mode=1
          waveshare_esp32s3_touch_lcd_128.build.cdc_on_boot=1
          waveshare_esp32s3_touch_lcd_128.build.msc_on_boot=0
          waveshare_esp32s3_touch_lcd_128.build.dfu_on_boot=0

but the schematics disagree. There, it has a CH343P USB-to-serial converter, and the ESP32-S3 feeds it via UART. Sneaky.

Please go into the waveshare_esp32s3_touch_lcd128.json and delete the line

        "-DARDUINO_USB_CDC_ON_BOOT=1",

then clean + upload + monitor again. Keep the settings for monitor_dtr and monitor_rts equal to 0.
