selftests: cgroup: add test_zswap with no kmem bypass test
Add a cgroup selftest that verifies memcg charging in zswap. The original
issue was that kmem bypass was applied to pages swapped out to zswap by
kswapd, resulting in zswapped memory not being charged. It was fixed by
commit cd08d80ecdac("mm: correctly charge compressed memory to its
memcg").
