Per-application memory.stat files are not available when per-application
memcgs are not used (per_app_memcg=false). Disable its usage based on
ro.config.per_app_memcg property.
minchan:
* correct indentation of memory_stat_parse
* move per_app_memcg check into memory_stat_parse inside
* change low_ram_device to per_app_memcg

* New clang compiler requires variadic function to have
at least one named parameter type.
* Use ##__VA_ARGS__ to work with empty __VA_ARGS__.
* Fix one ALOG_ASSERT parameter bug in lmkd/lmkd.c.

Setting memory.soft_limit_in_bytes on high-end devices with large memory
reserves affects performance of memory-hungry applications that have
large workingsets and keep thrashing because of the memory limits imposed.
Limit the usage of memory.soft_limit_in_bytes to low-memory devices only.
Add debug messages for future troubleshooting to capture cases when
vmpressure events are being ignored.

This reverts commit 5e60f88cab8a22d88d76f7fd49f5a6e9cc0d931b.
Reason for revert: broke some builds

Change-Id: I46bf6face35f5399d7d43146b360c0703eedfb1a
Logs that provide information about memory conditions during a process
kill event contain useful information and do not affect device
performance because these events are rare. Enabling them even when
ro.config.debug flag is not set will help in understanding low memory
conditions.

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

Bug: 78239479
Test: tested with alloc_stress, and saw logs written to statsd
