esp32: Fix USB deinit/reinit path via soft reset.HEADorigin/masterorigin/HEADmaster
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...
