Refactor comparison operations in geometry nodes

- Introduced a new `compare_node` function to streamline comparison operations across various geometry nodes.
- Replaced instances of mathematical comparison nodes with the new `compare_node` function in multiple files, enhancing code readability and maintainability.
- Updated related logic in cutout, depth surface, and image processing groups to utilize the new comparison method.
- Ensured consistent handling of boolean logic through the introduction of a `boolean_node` function for combining boolean inputs.
