Description
This PR improves ClickHouse LIKE pushdown for complex expressions in Trino.
LIKE with ESCAPE is out of scope of this PR.
Trino syntax for LIKE without ESCAPE does not support escape characters.
However Clickhouse supports escape with \ is for escaping literals %, _ and .
When Trino LIKE pattern contains \ do not pushdown the expression to Clickhouse.
