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

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.

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.

min_score_adjust should be set above PERCEPTIBLE_APP_ADJ to prevent such
