Add type generation support for geometric types (point, linestring, polygon)

This commit adds support for generating types for geometric attributes (POINT, LINESTRING, POLYGON) across all supported languages in the CLI type generation feature.

Type mappings:
- TypeScript/JavaScript: Array<number>, Array<Array<number>>, Array<Array<Array<number>>>
- C#/Dart/Java/Kotlin: List<double>/List<List<double>>/List<List<List<double>>>
- PHP: array (for all geometric types)
- Swift: [Double], [[Double]], [[[Double]]]

Changes include:
- Added POINT, LINESTRING, POLYGON to AttributeType enum
- Implemented type mapping logic for all language generators
