virtio: add low-level APIs for feature bits
Add low level APIs to test/set/clear feature bits. For use by transports, to make it easier to write code independent of feature bit array format. Note: APIs is prefixed with __ and has _bit suffix to stress its low level nature. It's for use by transports only: drivers should use virtio_has_feature and never need to set/clear features.
