ANDROID: sched/cpuset: Add vendor hook to change tasks affinity

Vendors might want to change tasks affinity settings when they are
moving from one cpuset into the other. Add vendor hook to give control
to vendor to implement what they need.

This reverts commit a42f6e7d("Revert "ANDROID: sched/cpuset: Add
vendor hook to change tasks affinity"") to effectively bring back the
original change.
