sched/psi: Move private helpers to sched/stats.h
This patch move psi_task_change/psi_task_switch declarations out of
PSI public header, since they are only needed for implementing the
PSI stats tracking in sched/stats.h
psi_task_switch is obvious, psi_task_change can't be public helper
since it doesn't check psi_disabled static key. And there is no
any user now, so put it in sched/stats.h too.
