usb/gadget: add USB serial connect and disconnect
The serial gadget can only work if the serial function is
properly connected on USB trigger (ie. on SET_CONFIGURATION
or SET_INTERFACE USB message triggering set_alt() in
composite.c).
Make this connection and handle also the disconnection in
f_serial.
