Suren Baghdasaryan 51ee4c505f lmkd: add kill when swap utilization is too high 
When non-swappable allocations cause memory pressure swap will not be
depleted, however a high percentage of the swappable memory will be
pushed into swap. Detect this condition and kill a process when swap
utilization is too high while under memory pressure.
Introduce ro.lmk.swap_util_max property to represent max percentage of
the overall swappable memory that can be swapped under memory pressure
without triggering a kill. ro.lmk.swap_util_max is set to 100 by default
which disables kills due to the swap utilization.

Test: ION memory hogger with ro.lmk.swap_util_max set to 95
