This patch adds the configuration MICROPY_HW_USB_ENABLE_CDC2 which enables a new USB device configuration at runtime: VCP+VCP+MSC. It will give two independent VCP interfaces available via pyb.USB_VCP(0) and pyb.USB_VCP(1). The first one is the usual one and has the REPL on it. The second one is available for general use. This configuration is disabled by default because if the mode is not used then it takes up about 2200 bytes of RAM. Also, F4 MCUs can't support this mode on their USB FS peripheral (eg PYBv1.x) because they don't have enough endpoints. The USB HS peripheral of an F4 supports it, as well as both the USB FS and USB HS peripherals of F7 MCUs.
