[PR] [spark] Prevent table deletion for self referencing RTAS [paimon]
ArnavBalyan opened a new pull request, #9139:
URL: https://github.com/apache/paimon/pull/9139
### Purpose
- A self referencing replace table on an existing table fails the query and accidentally performs a data drop.
- This is because Spark drops the table before evaluating the query. The query always fails while reading the deleted manifest leading to original table being lost permanently.
- Add guard to ensure this operation does not happen for partitioned table rtas and we can avoid data loss.
### Tests
- UT
