arm-autonomy: Create arm-autonomy-host feature

Create a new distribution feature to enable functionalities for autonomy host systems: - enable xen and ipv4 in distribution features - enable xen backend drivers in Linux kernel using a kmeta feature For the feature to work properly, create a class inherited when the layer is included to enable required parameters Change-Id: Ia0cdaa2b69bc030515ea16d67c47fec6b1ea0897 Issue-Id: SCM-767 Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com> Reviewed-by: Diego Sueiro <diego.sueiro@arm.com> Signed-off-by: Jon Mason <jon.mason@arm.com>
