sunxfancy abbda65c0c refactor(map): remove UWP platform support and enhance map projection tests 
- Removed UWP platform from the available build options in CMake.
- Deleted the UWP-specific CMakeLists.txt file.
- Added comprehensive tests for various map projection methods, including isometric and staggered projections, to ensure accurate tile-to-world and world-to-tile conversions.

These changes streamline the build configuration and improve the testing coverage for map projections.
