[PLAT-14539][xCluster] need_bootstrap API does not work for old unive…

…rses

Summary:
To improve the performance, YBA creates the main table to its index tables map using the indexed_table_id field that is part of the ListTables RPC. However, this field is only available for the universes with YBDB version after `2.21.1.0-b167`.

This diff makes changes to use the old method for old YBDB universes.

Test Plan:
- Create a universe at version `2.19.3.0-b122` and ensured the index table map is created properly.
- Create a universe at version `2.23.0.0-b490` and ensured the index table map is created properly and the more efficient method is used.
