Support more arguments for LEAD/LAG window functions

[xiangfu0]

Fix the LEAD/LAG window function implementation to match the SQL syntax.
Syntax:

LEAD(column_name, offset, default_value) OVER (PARTITION BY partition_column ORDER BY order_column)
LAG(column_name, offset, default_value) OVER (PARTITION BY partition_column ORDER BY order_column)

• column_name: The column from which to retrieve the value.
• offset: The number of rows forward from the current row to access. Default is 1 if not specified.
• default_value: The value to return if the offset goes beyond the number of rows.

Example:

SELECT 
    employee_id, 
    salary, 
    LAG(salary, 1) OVER (ORDER BY employee_id) AS previous_salary
FROM employees;
