refactor: Update Renderer Logic and Introduce Direct Pixel Access Methods

- Removed direct renderer calls from LoadLinkGraphics and LoadAllGraphicsData to prepare for future renderer refactor.
- Added LockTexture and UnlockTexture methods to IRenderer and SDL2Renderer for direct pixel access, enhancing texture management capabilities.
- Updated CMake configuration to include the new SDL2Renderer source file, ensuring proper integration within the graphics backend.
