Skip creating and renaming the old temp

Official CH changelog text
Skip creating and renaming the old temp table of non-append RMV DDLs in Replicated DBs. #84858 (Tuan Pham Anh).
Optimize Replicated DDL execution by skipping creation and renaming of old temporary tables for non-append RMV DDLs.

Why it matters

This feature improves the efficiency and performance of Replicated databases when executing non-append Remove (RMV) Data Definition Language (DDL) operations by avoiding unnecessary creation and renaming of old temporary tables. It simplifies and speeds up these DDL operations, reducing overhead and potential replication lag.

How to use it

The optimization is applied automatically for Replicated databases during execution of non-append RMV DDLs, requiring no manual configuration or changes from the user.
