-->
PartialSortExec had a missing functionality where it failed to detect slice
points when consecutive batches contained homogeneous sort key values (e.g.,
first batch: all rows with a=1, second batch: all rows with a=2). The
get_slice_point method only checked within individual batches, missing
cross-batch transitions.

* Modified the batching logic to accumulate incoming batches into a single
buffer before checking for slice points

is reached
