  [mlir][OpenMP] Fix teams reduction assert with sibling distributes (#191475)

Avoid double-mapping teams reduction block arguments when multiple
sibling `omp.distribute` ops appear under the same `omp.teams`.

Replace `teamsReductionContainedInDistribute` with
`getDistributeCapturingTeamsReduction`, which returns the unique
`omp::DistributeOp` containing all non-debug uses of the teams reduction
block arguments, or null if no such distribute exists. In that case,
reduction setup falls back to the teams op.

This ensures only the owning distribute handles reduction setup and
prevents `moduleTranslation.mapValue()` from being called multiple times
for the same block arguments.
