Refactored the shader compilation pipeline to introduce modularity, improve performance, and enhance maintainability. Key changes include:
- Added `ShaderCompilationConfig`, `CompilerOptimizeLevel`, and `ShaderStage` enums.
- Replaced `SM` property with `ShaderModel` in shader models.
- Introduced `ShaderLibrary` for in-memory and disk-based shader caching.
- Refactored `DSLShaderCompiler` and `AntlrShaderCompiler` for better hashing and error handling.
- Centralized shader compilation logic in `ShaderCompilerUtility`.
- Removed legacy shader compilation logic from `IShaderCompiler`.
- Updated `RenderGraph`, `ResourceManager`, and `Material` to integrate with the new caching system.
- Improved memory management with `NativeMemoryManager<T>`.
BREAKING CHANGE: Removed legacy shader compilation methods and replaced them with a new caching and compilation system.
Refactored shader system to support both graphics and compute shaders.
- Updated ANTLR grammars and parser logic for explicit shader model and compute shader entry points.
- Split shader models and descriptors for graphics and compute.
- Refactored pipeline key generation and D3D12 pipeline library for compute support.
- Updated push constant layouts and HLSL includes for both shader types.
- Improved error handling and test coverage with new example files.
BREAKING CHANGE: Shader model, descriptor, and pipeline APIs have changed. Existing shader and pipeline code must be updated to use the new types and conventions.
