[CARBONDATA-4316]Fix horizontal compaction failure for partition tables Why is this PR needed? Horizontal compaction fails for partition table leading to many delete delta files for a single block, leading to slower query performance. This is happening because during horizontal compaction the delta file path prepared for the partition table is wrong which fails to identify the path and fails the operation. What changes were proposed in this PR? If it is a partition table, read the segment file and identity the partition where the block is present to prepare a proper partition path. This closes #4240
