Suren Baghdasaryan bd3983c8a8 ANDROID: make per-cgroup PSI tracking configurable ...

With cgroup v2 hierarchy enabled PSI accounts stalls for each cgroup
separately and aggregates at each level of the hierarchy. That causes
additional overhead since psi_avgs_work would be called for each
cgroup in the hierarchy.
In Android we use PSI only at the system level, therefore this overhead
can be avoided.
Introduce CONFIG_PSI_PER_CGROUP_ACCT that controls per-cgroup PSI
tracking and is disabled by default.
