Amit Kapila b793a416bf Fix catalog lookup due to wrong snapshot for subtransactions during decoding. In commit `272248a0c`, we fixed the catalog lookup due to the wrong snapshot for transactions and subtransactions during decoding. We failed to consider the case where top-level xact is already marked as containing catalog change but its subtransaction is not yet marked as containing catalog change even though it contained such a change. This can happen when during decoding, none of the WAL records from the subtransaction was decoded and top-level xact contains a DDL. We fix it by marking the transaction and all its subtransactions as containing catalog changes if the top-level xact contains any catalog change and it is present in the initial running xacts array. This fix is required only for 14 and 15 because in prior branches we already always mark the transaction and all its subtransactions as containing catalog changes in the same case. In 16 and above, we preserve the list of transaction IDs and sub-transaction IDs, that have modified catalogs and are running during snapshot serialization, to the serialized snapshot (see commit `7f13ac8123`).
