CachedAppOptimizer: remove native freezer enabling code

Browse Source 
After merging the cgroup v2 uid/pid, processes are handled individually

not mapped to a profile anymore. For this reason all the related code
ought to be removed.

Bug: 181130874
Test: booted, verified freezer proper functioning
