Add a reusable uart-bridge driver that echoes data between two serial devices. It's mainly meant to be used with one of the devices being an USB CDC-ACM, the data is buffered, there's a pause feature to stop the USB endpoint when the hardware UART is filling up to avoid overrun and there's a helper function used to propagate the USB uart configuration to the hardware one.
