refactor: Refactor OpenGL backend to use OpenGLEnums

Browse Source 
Use centralized OpenGLEnums.h for enum conversion:
- Remove local ToGL* functions from OpenGLCommandList
- Replace with ToOpenGL() and ToOpenGLClearBuffer() from OpenGLEnums
- Simplify OpenGLTexture, OpenGLBuffer, OpenGLSampler, etc.
