Better error hints for non-existent tables

Why it matters

This feature enhances user experience by offering clearer, more informative guidance when a SELECT or other table-related query fails because the specified table is missing. It helps users quickly identify and resolve issues related to non-existent tables, reducing confusion and debugging time.

How to use it

The improved table-not-exist hints are enabled automatically in ClickHouse versions including and after this update. Users do not need to change any settings to benefit from more descriptive error messages when referencing non-existent tables.
