rootdir: Add cgroups and task profiles description files Add cgroups.json and task_profiles.json file to be places under /etc/ on the device to describe cgroups to be mounted and task profiles that processes can request. This adds additional layer of abstraction between what a process wants to achieve and how system implements that request.

libprocessgroup: introduce optional attribute for cgroup controllers Memory cgroup controller is not used by high-end Android devices and is disabled in Android kernels 5.10+, however Android Go devices still require this controller. Similarly schedtune controller is being replaced with cpu controller's utilclamp feature, however some devices are using older kernels which only support schedtune. To prevent spamming logcat with errors we need a way to mark a controller optional in such cases without removing it from cgroups.json file. Introduce "Optional" attribute to cgroup controller's cgroups.json description to accomodate these cases. When an optional controller fails to mount due to lack of support in the kernel it will log an informational message without generating further errors.

Fix cgroup directory permissions Cgroup attributes are set from three different contexts: (1) From the process that creates the cgroup directories. These processes are /system/bin/init, zygote and zygote64. (2) From the created process. Some but not all created processes have user ID and/or group ID 'system'. (3) The system_server process modifies certain cgroup attributes from other processes. Allow all processes from the system group, including system_server, to modify cgroup attributes from other processes. As one can see in init.rc, that file includes commands for granting the system group write permission for blkcg attributes.
