Add boot completed cmd to LMKD
...
Add new command to allow for post-boot actions to occur. This
will allow for the MemEventListener to start after the BPF files are
loaded, removing the need to stall during boot-up until they are loaded
in the device.
Test: Verified memevent listener initialized post-boot
Test: Verified LMKD no longer stalls until BPF progs are loaded

lmkd: Kill cached apps when thrashing or below low watermark
...
With Android U removing AMS kills, lmkd has additional duty to kill
cached apps which previously were killed by AMS. The former logic is
not proactive enough and leads to too many cached apps contributing
to memory pressure.
Implement additional logic to kill cached apps (excluding previous
foreground apps) when low watermark is breached or when device is
thrashing.

lmkd/tests: handle reordering of killing and reaping reports in the logs
...
Since killing and reaping of a process is done in separate threads, it's
possible that the reaping report will be ordered before the kill report.
Adjust the test to handle this case by checking for the reaping report
in the entire log output.
