OpenGL: Add a set of version and context specific OpenGL classes

This commit adds part of the output of utils/glgen and some simple
modifications to QOpenGLContext to allow easy access to classes
containing functions specific to a given OpenGL context and version.

This allows compile-time detection of mis-use of OpenGL features.
For example, trying to use glBegin(GL_TRIANGLES) with an OpenGL 3.2
Core Profile context will be detected by the compiler rather than at
runtime.

These capabilities make it much easier to add functionality to Qt and
applications that relies upon core features of OpenGL from specific
versions e.g. geometry shaders.
