sched: Add helper to block retained proxy donors
Scheduler ownership changes may need to turn a mutex-blocked task
retained on the runqueue for proxy execution back into a normally
blocked task.
Add sched_proxy_block_task() to perform that transition while holding
p->pi_lock and the task's runqueue lock. Reset an active donor to the
physical current task before blocking it. If DELAY_DEQUEUE keeps a FAIR
donor queued, the immediately following sched_change_begin() completes
the dequeue through switching_from_fair() before recording its queued
state.
This is a preparatory change to support proxy execution with sched_ext.
