cgroup: Add a new helper for cgroup1 hierarchy
A new helper is added for cgroup1 hierarchy:
- task_get_cgroup1
Acquires the associated cgroup of a task within a specific cgroup1
hierarchy. The cgroup1 hierarchy is identified by its hierarchy ID.
This helper function is added to facilitate the tracing of tasks within
a particular container or cgroup dir in BPF programs. It's important to
note that this helper is designed specifically for cgroup1 only.
