Refactor D3D12 Resource Management

Refactored and renamed components related to D3D12 graphics programming, replacing "descriptor" with "viewGroup" to improve resource grouping and management. Updated `D3D12CommandBuffer`, `D3D12DescriptorAllocator`, and `D3D12PipelineLibrary` to reflect these changes. Simplified material and shader creation in `D3D12ResourceAllocator`. Enhanced `D3D12ResourceDatabase` with resource naming for debugging and improved management. Refactored `Shader` and `ShaderPass` to use modern C# features and `IResourceReleasable` interface. Introduced `D3D12Utility` for centralized utility methods. Updated `Material` class for efficient buffer creation. Renamed `ShaderCompiler` to `SDLCompiler` with improved error handling. Updated `MeshRenderPass` to use new shader compilation process. Various improvements in error handling, code readability, and utility methods.
