plugin-api: resourced: Add working set size related info in task_info

resourced requires active, inactive, and swap memory size,
because working set size-based resourced-lmk-governor should know them
to calculate memory efficiency of each app.
Normally, this information is located in memory.stat of memcg.
In addition, some apps are free from LMK according to working set size.
