Add geospatial dimensions support

[kaspersjo]

This PR adds support for geospatial dimensions, initially two types are supported POINT and POLYGON.

In the ClickHouse connector the support is based on the Point and Polygon types and in DuckDB it's based on the POINT_2D and POLYGON_2D types.

Checklist:

• Covered by tests
• Ran it and it works as intended
• Reviewed the diff before requesting a review
• Checked for unhandled edge cases
• Linked the issues it closes

• Intend to cherry-pick into the release branch
• I'm proud of this work!

Can you also update runtime/parser/schema/project.schema.yaml with the new dimension type: property and run make docs.generate?
