Added Support for Temporary Tables in ATTACH and REPLACE PARTITION Queries

Why it matters

This feature allows greater flexibility in managing partitions by enabling users to specify temporary tables as the source in partition attachment or replacement operations. It simplifies workflows where data is prepared or staged in temporary tables before being merged into main tables.

How to use it

Users can specify a temporary table directly in the FROM part of ATTACH PARTITION FROM or REPLACE PARTITION FROM queries, allowing partition data to be sourced dynamically from those temporary tables during partition operations.
