RFR: 8201362: Remove CollectedHeap::barrier_set()

This patch removes the redundant CollectedHeap::_barrier_set and the
setter/getter. Throughout the code, we currently have a mix of calls to 
BarrierSet::barrier_set() and Universe::heap()->barrier_set(). This 
patch unifies all that to always use BarrierSet::barrier_set().
