mimxrt: Add USB ID elements. 

- Manufacturer, set by MICROPY_HW_USB_STR_MANUF; default "MicroPython"
- Board name, as set by MICROPY_HW_BOARD_NAME
- Unique-ID, same as returned by machine.unique_id()
- USB Vendor ID, as set by MICROPY_HW_USB_VID; default 0xf055
- USB Product ID, as set by MICROPY_HW_USB_PID; default 0x9802
