Disable colorize logging of SQL and reduce unnecessary invokation of sql_color matching

When the `colorize_logging` is disabled,
logs do not colorize the SQL queries.
But the `sql_color` method is always
invoked which due to regex matching results
in slow queries.

This PR fixes #38685 and removes
unnecessary invokation of `sql_color`
method when `colorize_logging` is disabled
