[TABLE MODEL] Implement CREATE/SHOW/DROP Function and user-defined scalar function

[Cpaulyz]

Description

https://timechor.feishu.cn/docx/GXnNdt3XIok3CQxBvwWcZxrnntd

This pull request introduces several new user-defined functions (UDFs) and corresponding integration tests for the IoTDB project. The changes include the addition of new scalar functions, updates to existing classes, and the creation of new test cases to ensure the functionality and robustness of the UDF management system.

New Scalar Functions:

• ScalarFunctionExample: Implements a scalar function that checks if any input value is null and returns a boolean result.

Integration Tests:

• IoTDBSQLFunctionManagementIT: Adds multiple test cases to verify the creation, display, and deletion of scalar functions, including handling of invalid function names and URIs.
