Refactor geometry node groups for image depth processing

- Introduced new utility functions in common nodes for evaluating fields and capturing attributes.
- Simplified volume field calculations in image depth cutout and panorama groups by utilizing new utility functions.
- Enhanced readability and maintainability of the image depth cutout and panorama node groups by removing redundant code and improving function usage.
- Adjusted default values for thickness and depth scale in image relief plane group for better user experience.
- Improved handling of geometry attributes and connections in image depth plane group to streamline processing.
