Refactor rendering architecture and replace rasterizer with renderer

Browse Source 
- Introduced SoftwareRenderer as a pixel-accurate software rendering backend.
- Removed the obsolete wolf_3d_rasterizer.dart file.
- Created a new wolf_3d_renderer.dart file to centralize rendering exports.
- Updated tests to accommodate the new rendering structure, including pushwall and projection sampling tests.
- Modified the WolfAsciiRenderer and WolfFlutterRenderer to utilize the new SoftwareRenderer.
- Enhanced enemy spawn tests to include new enemy states.
