  [mlir][OpenACC] Match reuse barriers to the reused private scope (#225570)

A region that writes both gang- and worker-private slots was considered
to be a gang scope and a barrier was missed. This change keeps the two
store sets separate and pick the barrier from the scope that is actually
reused. Follow-up for
