feat: Add MoGe-2 surface generation and export functionality

- Introduced new enum items for depth plane and surface models with caching.
- Added MOGE2_MESH_JOB to operators for converting images to surfaces.
- Implemented surface mesh building and exporting in RunJob operator.
- Enhanced UI to include export format options for MoGe-2.
- Created validation tools for MoGe-2 surface assets and depth planes.
- Updated geometry nodes to support new surface generation features.
- Refactored existing tests to accommodate new functionality and ensure stability.
