Review Comment:
I see one usage in `SegmentAssignmentUtils.getPartitionId()` used by
`ReplicaGroupSegmentAssignmentStrategy` for assigning offline segments.
I think we can fail fast here if column partition and
uploadedSegmentPartitionId both are provided as `uploadedSegmentPartitionId` is
more for keeping the assignment same as stream partitions for upserts but it
does not make sense for an offline table.
Open to better name suggestion for `uploadedSegmentPartitionId` in case it
sounds misleading.
