sched/cache: Add migrate_llc_task migration type for cache-aware balancing
Introduce a new migration type, migrate_llc_task, to support
cache-aware load balancing.
After identifying the busiest sched_group (having the most tasks
preferring the destination LLC), mark migrations with this type.
During load balancing, each runqueue in the busiest sched_group is
examined, and the runqueue with the highest number of tasks preferring
the destination CPU is selected as the busiest runqueue.
