init: Add task_profiles init command
Introduce new command to allow setting task profiles from inside .rc
script. This is to replace usage of writepid when a service is trying
to join a cgroup. Usage example from a .rc file:
service surfaceflinger /system/bin/surfaceflinger
task_profiles HighPerformance
Bug: 155419956
Test: change .rc file and confirm task profile is applied
