Enhance OpenGLBuffer with more buffer types and features

- Add OpenGLBufferType enum (Vertex, Index, Uniform, CopyRead, CopyWrite, etc.)
- Add Initialize() method with buffer type parameter
- Add Map/Unmap for direct buffer access
- Add SetData for dynamic updates
- Add BindBase for buffer binding to indexed targets
- Add GetType and IsDynamic getters
