feat(c/sedona-geos): Implement item crs support for GEOS-based kernels

[paleolimbot]

A continuation of #492 for c/sedona-geos. 2/3 PRs to address #487 (c/sedona-tg, c/sedona-geoarrow-c remain).

Pull request overview

This PR implements item CRS (Coordinate Reference System) support for GEOS-based geometry kernels in Apache Sedona, enabling these functions to work with geometries that have embedded CRS information.

Changes:

• Modified all GEOS kernel implementations to return Vec<ScalarKernelRef> instead of single ScalarKernelRef, wrapping implementations with ItemCrsKernel::wrap_impl()
• Added comprehensive test coverage for item CRS support across all affected functions
• Refactored the registration system to use declarative macros for cleaner kernel registration
