[MLIR][Vector] Enhance vector.multi_reduction unrolling to handle scalar result (#188633 )

Previously, UnrollMultiReductionPattern bailed out when all the
dimensions were reduced to a scalar. This PR adds support for this case
by tiling the source vector and chaining partial reductions through the
accumulator operand.
