samples: cdc_acm: add DT overlay to support snps,dwc2 on nucleo_f413zh

Add DT overlay to be able to support and test usb_dc_dw driver (snps,dwc2) on nucleo_f413zh board. This disables STM32 shim driver described and configured on the SoC and board level. Obviously,it works with other STM32F4 boards as well, but we do not have a mechanism to apply it generically yet, upcoming snippet support may fix that. Until then, we need something for development and as an example. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>
