Refactor error handling and improve type safety

Refactored error handling across the codebase by replacing exceptions with `Result`-based error handling for better robustness and consistency.

- Updated `ResultExtensions` to use `EqualityComparer` for comparisons.
- Enhanced `RenderingContext` with `GetValueOrThrow` for resource validation and added type constraints for texture methods.
- Introduced `CommandError` and `RecordError` in `D3D12CommandBuffer` for improved error tracking.
- Refactored `D3D12ResourceDatabase` to use `Result` objects for resource queries.
- Updated `ICommandBuffer` and `IResourceDatabase` interfaces to return `Result` objects.
- Improved type safety by replacing `int` with `uint` where appropriate.
- Simplified texture handling in `MeshRenderPass` with new `CreateTexture` logic.
- Cleaned up project files by removing unused and redundant entries.

These changes enhance code maintainability, improve error reporting, and ensure type safety throughout the project.
