Update capabilities for QEMU 8.1 on s390x, add a new capability
async-teardown and make use of it when running on s390x hosts to improve
memory reclaiming.
Is this really something that should be enabled unconditionally on all
s390x guests, or should it be configured with some domain xml? If
there's ever a case where an s390x domain would want this disabled, I
think it would have to be configurable. Also, if there is any situation
where a domain on a different architecture might want to enable this,
that would also require some kind of configurability. At minimum it
seems to me that the commit log should have a lot more justification for
why this approach is justified.
