[SPARK-33862][SQL] Throw PartitionAlreadyExistsException if the target partition exists while renaming

### What changes were proposed in this pull request?
Throw `PartitionAlreadyExistsException` from `ALTER TABLE .. RENAME TO PARTITION` for a table from Hive V1 External Catalog in the case when the target partition already exists.

### Why are the changes needed?
1. To have the same behavior of V1 In-Memory and Hive External Catalog.
2. To not propagate internal Hive's exceptions to users.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the partition renaming command throws `PartitionAlreadyExistsException` for tables from the Hive catalog.

### How was this patch tested?
Added new UT:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *HiveCatalogedDDLSuite"
```

Closes apache#30866 from MaxGekk/throw-PartitionAlreadyExistsException.
