OpenGL Renderer: Add new rendering resource classes, and do some misc. refactoring. 

- Using the new OpenGLGeometryResource and OpenGLRenderStatesResource classes, the 3.2 Core Profile and ES renderers now use triple-buffering for all geometry rendering resources and framebuffer constants.
- Delete the InitFinalRenderStates() method, which has been obsoleted over the years. Its functionality has been rolled into the InitExtensions() and _RenderGeometryLoopBegin() methods.
