OpenGL: Add missing WINAPI calling convention for QGL functions

This is the QGL equivalent of commit

602cab9bb2072c5564bbb43c4125e04f98266043

Without this QGLExtensionMatcher causes stack corruption when using
a core profile GL context due to the call to glGetStringi() with
an incorrect calling convention.
