Added a setting delta_lake_enable_expression_visitor_logging

Why it matters

Expression visitor logs can be extremely verbose, even at the test log level, which complicates debugging by overwhelming the log output. This setting allows users to disable these verbose logs to reduce noise and improve log clarity during debugging.

How to use it

Set the delta_lake_enable_expression_visitor_logging setting to 0 (off) to disable expression visitor logging or 1 (on) to enable it. The setting can be applied in the user profile or session settings, for example:

SET delta_lake_enable_expression_visitor_logging = 0;
