vulkan-cereal: host-common: add external ASG creation

The ASG ring buffer is created via posix_mem_align(..), which
could be essentially malloc.

For vhost-user cases where sandboxing is used, one may want an
OS specific mechanism to create the ASG ring buffer from external
memory.  On Linux systems, that's typically memfd_create(..).
