[fix](search) add restriction for search function

[airborne12]

What problem does this PR solve?

Issue Number: close #xxx

Related PR: #56139

Problem Summary:
This PR adds restrictions for the search() function to ensure it can only be used in WHERE clauses on single-table OLAP scans. The implementation includes validation rules that reject search() usage in other contexts like SELECT projections, GROUP BY clauses, HAVING clauses, and multi-table scenarios.

Pull Request Overview

This PR adds restrictions for the search() function to ensure it can only be used in WHERE clauses on single-table OLAP scans. The implementation includes validation rules that reject search() usage in other contexts like SELECT projections, GROUP BY clauses, HAVING clauses, and multi-table scenarios.

• Added a new analysis rule CheckSearchUsage that validates search() function usage patterns
• Created comprehensive unit tests covering valid and invalid search() usage scenarios
• Integrated the validation rule into the analyzer pipeline before other optimizations
