mm: memcontrol: move memsw charge callbacks to v1
The interweaving of two entirely different swap accounting strategies has
been one of the more confusing parts of the memcg code. Split out the v1
code to clarify the implementation and a handful of callsites, and to
avoid building the v1 bits when !CONFIG_MEMCG_V1.
