Distinguish KILL MUTATION for Different Tables to Fix Cancelled Mutating Parts Error

Distinguish KILL MUTATION for different tables (fixes unexpected Cancelled mutating parts error). #25025 (Azat Khuzhin).
Distinguish KILL MUTATION commands for different tables to prevent unintended cancellation errors during mutation execution.

Why it matters

This feature addresses the issue where executing KILL MUTATION could mistakenly cancel mutations on other tables, resulting in unexpected Cancelled mutating parts errors. By differentiating KILL MUTATION commands per table, it ensures mutations are managed accurately and independently, improving mutation reliability.

How to use it

Continue using the KILL MUTATION command as usual. This improvement automatically scopes the kill requests to the specific table involved in the mutation, requiring no additional configuration or user intervention.
