Add geometry nodes asset and validation script

- Implemented a new geometry nodes asset in `build_geometry_nodes_asset.py` to handle mesh refinement and topology fixing.
- Created a validation script in `validate_geometry_nodes_asset.py` to ensure the integrity and functionality of the geometry node group.
- Added input handling for various parameters including resolution, iterations, and smoothing options.
- Included checks for node group structure and attributes to validate the geometry processing pipeline.
