Suren Baghdasaryan fa667edb56 lmkd: Add lmkd wakeup information into killinfo logs 
Oftentimes while investigating bugreports it's unclear whether lmkd
was active between kills. To provide visibility into lmkd activity
adding the following fields into killinfo reports:
MsSinceEvent - number of msecs since the last PSI/vmpressure event
MsSincePrevWakeup - number of msecs since the previous wakeup
WakeupsSinceEvent - number of wakeups since the last PSI/vmpressure
event
SkippedWakeups - number of wakeups that were skipped due to an
incomplete kill

Suren Baghdasaryan dd8c2c181b lmkd: Set default kill timeout to limit waits for uninterruptible processes 
When lmkd tries to kill a process in uninterruptible sleep state, it may
need to wait for a long time. To prevent this set the default kill timeout
to 100ms which should work for majority of the devices.

Suren Baghdasaryan 7afa463978 lmkd: Do not kill perceptible apps due to low swap if above min wmark 
Prevent kills of perceptible apps due to swap shortages unless system
free memory is below the min watermark. This prevents kills of important
apps when the system is recovering from the memory pressure.

Bug: 155709603
Test: memory stress test with multiple foreground apps
