feat(shader): refactor and enhance shader pipeline

Browse Source 
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.
