Add Output Format Pretty Max Value Width Setting

Why it matters

This feature addresses the issue of very large values causing overly wide output in terminal displays, which can be difficult to read and manage. By truncating values that exceed a specified width, it improves readability and usability of query results in the terminal.

How to use it

Set the output_format_pretty_max_value_width setting to a desired maximum width (integer) to limit the length of values displayed in pretty formatted output. Values longer than this setting will be cut off. Example:

SET output_format_pretty_max_value_width = 50;
SELECT * FROM table FORMAT Pretty;
