OpenGL: Add versioned functions support for opengl 4.4 and 4.5

Previous errors in versioned function classes for OpenGL versions
prior to 4.4 have also been fixed to comply with the new OpenGL
xml specification. Such mistakes were due to either bugs in the
old plain text specification files or problems due to the
difficulty in parsing the old spec files.

In some cases this has meant adding in missing functions that were
absent previously.

The other class of problem was when functions were erroneously
included in the versioned function classes when they should not
have been present. That is, some core profile classes incorrectly
had member functions for deprecated functions that should only
be present in the compatibility profile classes. In these cases
these incorrect functions will now trigger a qFatal if
called. This is fine as any applications that called these by mistake
in the past would have been dereferencing a null pointer as the
function pointer resolution would have failed for these functions.

[ChangeLog][QtGui] Add version function classes for OpenGL 4.4 and 4.5
and deprecate some erroneously classified functions.
