Remove::__1 from Stacktraces and Display std::basic_string as String

Official CH changelog text
Remove ::__1 part from stacktraces. Display std::basic_string<char, ... as String in stacktraces. #47171 (Mike Kot).
Improves stacktrace readability by removing the ::__1 part and simplifying the display of C++ standard string types to String.

Why it matters

This feature enhances the clarity and usability of stacktraces by eliminating unnecessary template suffixes (::__1) and rendering complex C++ std::basic_string<char, ...> types as String, making debugging easier and more intuitive for users.

How to use it

Users benefit from this improvement automatically when viewing stacktraces in ClickHouse after upgrading to the version containing this fix; no additional configuration or actions are required.
