This avoids a race between destruction on process exit and concurrent
access from another thread.

Vendors should be able to specify additional cgroups and task profiles
without changing system files. Add support for /vendor/etc/cgroups.json
and /vendor/etc/task_profiles.json files which will augment cgroups and
task profiles specified in /etc/cgroups.json and /etc/task_profiles.json
system files.

lmkd uses set_sched_priority to expedite killing of its victims and this
sometimes results in timerslack_ns writes for an process which is already
dead. These messages are detrimental during troubleshooting and do not
indicate a real problem, therefore need to be suppressed.

File descriptor caching breaks boot on Android Go and Svelte targets.
Disable it temporarily to fix the builds and investigate the root cause
further.

Non-Android build targets are missing sys/prctl.h header and functionality
should be disabled for them like it was done previously inside
sched_policy.cpp. Also make the set_sched_policy/get_sched_policy
functionality backward compatible by creating stubs for non-Android
targets.

Abstract usage of cgroups into task profiles that allows for changes
in cgroup hierarchy and version without affecting framework codebase.
Rework current processgroup and sched_policy API function implementations
to use task profiles instead of hardcoded paths and attributes.
Mount cgroups using information from cgroups.json rather than from init.rc
