Rework virtio-aarch64 machine definition
Start on potentially removing separate virtio-arch64 machine by simplifying it and moving as much of its virtio kernel configuration over to our generic kernel configuration scheme. From some experimentation, it is not obvious that genericarm64 or qemuarm64 are directly reusable as guest MACHINEs as is, so further investigation is required on whether maintaining our own machine and potentially custom kernel metadata cache is perhaps worthwhile. Changes: - Update virtio-aarch64 linux-yocto bbappend for new version in scarthgap, and drop its use of a custom kernel metadata cache for reusing qemuarm64's BSP as a starting point for now. - Move the various virtio-*.cfg kernel configuration fragments over to meta-agl-core, using a new "agl-virtio-guest" AGL_FEATURES flag to control whether they are used. The aim is to make it more obvious where any virtio kernel configuration comes from and hopefully make it more easily reusable.
