OpenGL: More changes in preparation of OpenGL ES. 

- Slightly change the names of attachment defines so that they can be distinguished from the native OpenGL attachment defines.
- The minimum version driver check now accounts for OpenGL ES.
- OpenGLRendererCreate() can now handle any possible OpenGL variant, as declared in the OpenGLVariantID enum.
- Framebuffer read backs may now assigned their format and data type. (Legacy OpenGL assigns the format as GL_BGRA, while 3.2 Core Profile assigns the format as GL_RGBA.)
