This reverts commit bee9f5718b
"libprocessgroup: Disable file descriptor caching temporarily" and adds
option to use SetTaskProfiles and SetProcessProfiles without file caching.
This option is used from JNI to avoid access denials because cached files
are not whitelisted for JNI usage.

Some app may have different cgroup settings in cpuset and schedtune for its
threads, so let blkio follow cpuset only, which represents the app's current
state more accurately. Otherwise, if that thread is doing IO, then its
performance will be affected because its blkio group is in lower priority
group as schedtune.
ex: an app is now in top-app, but some thread of it set schedtune group to
background, and blkio follows schedtune because it is called later.
Main thread:
6:schedtune:/top-app
5:memory:/
4:cpuset:/top-app
3:cpuacct:/uid_1000/pid_8766

1:blkio:/

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.

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
