Fix the stats log in lmkd
1. let logs be written to statsd directly like all other stats logs.
+ stats log should not write to logd anymore(b/78239479)
2. fixed the log format
+ need to embed the elapsed real time in the log
3. fixed the log context reuse problem
+reset the log context buffer and internal state before reuse

lmkd: move sundry pieces to statslog.h
Pragma once is not part of the standard, and is actually a gnu
C++ addition. Android coding standard requires the #ifndef header
wrappers. Moved things that belong in statslog.h from the lmkd files.
SideEffects: None
Test: lmkd_unit_tests

Implement stats logging in LMKD.
It implements logging of following atoms:
-- LMK_STATE_CHANGED
-- LMK_KILL_OCCURRED
We would like to gather memory metrics of the process killed by LMKD
because by gathering this info we would be able to analyze and improve
system health by potentially reducing memory footprint of the process.
This feature would be available on production builds.
To know more about this see: http://go/android-p-memory-metrics
