lib: virtio: Rework macros VIRTIO_ROLE_IS_DEVICE and VIRTIO_ROLE_IS_D…

…RIVER The virtio.h header can be included by applications. In such cases, VIRTIO_DRIVER_SUPPORT and VIRTIO_DEVICE_SUPPORT, which are used to optimize the library, may not be defined in the application. Define default VIRTIO_ROLE_IS_DEVICE and VIRTIO_ROLE_IS_DRIVER macros that do not check for VIRTIO_DEVICE_SUPPORT or VIRTIO_DRIVER_SUPPORT if they are not defined.
