close #12091 This PR tries to fix the assertion error in the sized hash join by explicitly concatenating multiple batches into a single one. The original code expects only one batch in the input iterator for the build side of a small join, but it is not true when split-retry happens in the previous operator (e.g. GpuHashAggregate), and the GPU path in this sized join does not concatenate these small batches, instead passes them directly down to this `getSingleBuildBatch` function. Then the assertion fails. One more thing, in the failing case, the join has an exchange and an aggregate as the children.  --------- Signed-off-by: Firestarman <firestarmanllc@gmail.com>
