Add a function similar to sample_usbd_init_device(), but one that does
not initialize the device. It allows the application to set additional
features, such as additional descriptors.

There is common code for the new USB device support in the samples to
instantiate USB device, descriptors, configuration and initialize USB
device. Add common code that can be used for the simple usecase with a
single USB device and single configuration.
