{Memory,Swap}Meter: add "compressed memory" metrics
For now, the semantics are mostly fit for Linux zswap subsystem. For
instance, we add the third swap usage metric that indicates the amount
of memory that is accounted to swap but in fact stored elsewhere. This
exactly matches the definition of frontswap/zswap, and is probably of
little use to all other platforms.
