sched: Misc preps for cgroup unified hierarchy interface
Make the following changes in preparation for the cpu controller interface implementation for cgroup2. This patch doesn't cause any functional differences. * s/cpu_stats_show()/cpu_cfs_stat_show()/ * s/cpu_files/cpu_legacy_files/ v2: Dropped cpuacct changes as it won't be used by cpu controller interface anymore.
