mm: memcontrol: drop dead CONFIG_MEMCG_SWAP config symbol
Since 2d1c498072de ("mm: memcontrol: make swap tracking an integral part
of memory control"), CONFIG_MEMCG_SWAP hasn't been a user-visible config
option anymore, it just means CONFIG_MEMCG && CONFIG_SWAP.
Update the sites accordingly and drop the symbol.
[ While touching the docs, remove two references to CONFIG_MEMCG_KMEM,
which hasn't been a user-visible symbol for over half a decade. ]
