Adds proper support for running multiple CDC ports at once. Currently targeted to support no more than two at the same time. By default, Arduino supports only one, but with some changes to the lib-builder, support for two can be added.

Lib-builder: espressif/esp32-arduino-lib-builder#275
Fixes: #10936
