Add sampler support and refactor resource handling

Enhanced shader and resource systems with `Sampler` support, including updates to `ShaderPropertyType`, HLSL code, and resource management. Refactored `Result` structs for better type safety and added new enums for texture and comparison settings. Improved `MeshRenderPass` to dynamically load textures and samplers. Updated SDL compiler and token lexicon for `Sampler` handling. Embedded debug info in project files and streamlined resource state tracking.
