Removed stderr logging for invalid/complex regex in re2 library

Why it matters

To eliminate unwanted or noisy logs written to stderr by the re2 library when users input invalid or overly complex regular expressions. This improves user experience by reducing unnecessary log clutter and focusing only on relevant ClickHouse logs.

How to use it

This change is internal and automatic; users do not need to take any action. Invalid or complex regular expressions will no longer generate stderr logs from the re2 library during query execution.
