feat(render): refactor pipeline & shader system for DX12 WG

Major refactor of render pipeline and shader system:
- Replaced legacy shader properties with source generator and attribute-based HLSL struct generation.
- Introduced ShaderPropertiesRegistry for runtime property layout/code registration.
- Added modular IRenderPipeline, IRenderPipelineSettings, and IRenderPayload interfaces.
- Implemented GhostRenderPipeline and ECS-driven GPUScene management.
- Added experimental DirectX 12 Work Graph support.
- Refactored shader compilation, variant hashing, and caching.
- Updated APIs for consistency and improved codegen for registration.

These changes modernize the rendering infrastructure for advanced features like work graphs and dynamic pipelines.

BREAKING CHANGE: Shader DSL, pipeline, and property APIs have changed. Existing shaders and pipeline integrations must be updated.
