6aaf89e603 Add OpenGL backend: OpenGLDevice class 
- Created OpenGLDevice class for window and OpenGL context management
- Added CreateWindow() and InitializeWithExistingWindow() methods
- Integrated with GLFW and GLAD
- Added to tests/OpenGL as test target

This is the first step in building the OpenGL RHI backend parallel to D3D12.
