kabi: reserve space for cpu cgroup and cpuset cgroup related structures

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4GII8?from=project-issue


CVE: NA

--------

We reserve some fields beforehand for cpu cgroup and cpuset related structures
prone to change, therefore, we can hot add/change features of cpu cgroup cpuset
and cgroup with this enhancement.

After reserving, normally cache does not matter as the reserved fields
are not accessed at all.
