Formatting of SQL Function Parameters with Keyword Elements

[xterao]

Overview

This PR fixes formatting issues that occurred when combining function names (treated as keyword elements) and other keyword elements within SQL function parameters. Previously, line breaks and indentation were not handled correctly in such cases.

Changes

• When determining a FUNCTION_NAME element as a function name block, the logic now checks if the next non-whitespace element is a LEFT_PAREN. If not, it is treated as a regular keyword block.
• Fixed the indentation calculation logic when a conditional loop directive exists immediately before a function name block.
  In the PreProcessor, the condition to prevent line breaks after a function name is now applied only to LEFT_PAREN, not to other elements.

These changes improve the formatting of SQL code involving function parameters and keyword elements, ensuring correct line breaks and indentation.

Pull Request Overview

This PR fixes SQL formatting issues when combining function names (treated as keyword elements) with other keyword elements within SQL function parameters. The changes ensure proper line breaks and indentation are maintained in such scenarios.

• Improved function name detection by checking if a FUNCTION_NAME element is followed by a LEFT_PAREN
• Fixed indentation calculation for function parameters, especially when conditional loop directives are present
• Enhanced the preprocessing logic to handle line breaks after function names more precisely
