Add a new QEMU config for kunit_tool, x86_64-smp, which provides an 8-cpu SMP setup. No other kunit_tool configurations provide an SMP setup, so this is the best bet for testing things like KCSAN, which require a multicore/multi-cpu system.
The choice of 8 CPUs is pretty arbitrary: it's enough to get tests like KCSAN to run with a nontrivial number of worker threads, while still working relatively quickly on older machines.

I know there is some discussion on this patch, but I think this patch is good as implemented; we could always delete this config if we change our policies later.
