qapi: introduce device-sync-config
Add command to sync config from vhost-user backend to the device. It
may be helpful when VHOST_USER_SLAVE_CONFIG_CHANGE_MSG failed or not
triggered interrupt to the guest or just not available (not supported
by vhost-user server).
Command result is racy if allow it during migration. Let's not allow
that.
