Fixes problems with USB-CDC state after soft reset if USBDevice has been active with the default USB-CDC driver also enabled. This also brings ESP32 behaviour in line with RP2 and other ports, where boot.py is executed before the runtime USB device is initialised. This allows setting up a custom USB device in boot.py. There is still a bug here, because calling tud_disconnect() doesn't cause any UNPLUG or BUS_RESET events to arrive from TinyUSB - which means the USB device state stays out of sync until we call mp_usbd_init() again...
