DAOS-19429 rebuild: add global EC aggregation barrier
1d4e28a 
Rebuild currently pauses EC aggregation only on each local target, without
waiting for all targets globally. In CI, EC aggregation was observed more
than 90 seconds after rebuild had started pausing it.

Add a global EC aggregation barrier without introducing a new rebuild
phase. Each target reports through the existing rebuild IV after its local
EC aggregation has stopped. Once all participating targets have reported,
the rebuild leader publishes the stable epoch and allows scanning to start.
