Use the LL-NDK library to read cgroup.rc.
As a side-effect, the CgroupController class is changed
to a wrapper of ACgroupController* from the library. The
class itself essentially becomes the pointer, and can be
trivially copied. Modify all client code for this change.

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.

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

We want our default implementations to fail, but '-1' is implicitly
cast to 'true', since it's non-zero. We explicitly use 'false' to
fix this.

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
