System Log Tables Default to Polymorphic Parts

System log tables now use polymorpic parts by default. #9905 (Anton Popov)
System log tables in ClickHouse now use polymorphic parts by default.

Why it matters

This feature improves the storage and management of system log tables by enabling polymorphic parts by default, which allows more efficient handling of different data parts and potentially enhances performance and flexibility in system log operations.

How to use it

No explicit action is required from users as system log tables have been updated to use polymorphic parts by default. Users can continue using system log tables as usual with the benefit of this internal improvement.
