Suren Baghdasaryan 4787ab452f lmkd: Use aggregate zone watermarks as low memory threshold 
Parsing /proc/zoneinfo is expensive and zone watermarks normally do no
change often. Instead of checking free memory per each zone we aggregate
zone watermarks and compare them with MemFree from meminfo as an
approximation of memory being under a given watermark.
zoneinfo parsing is rate limited to once per minute to detect a possible
change of the memory margins from userspace.

Bug: 132642304
Test: lmkd_unit_test, ACT memory pressure tests
