Remove deprecated QGL* classes

Removes QGL paths in sub-attaq and chip examples.

The boxes example depended on QGL and has been removed.

The corresponding module and test directories for the opengl module are now
empty, but has been left there so we can move the QOpenGL* classes there.

[ChangeLog][QtOpenGL] The deprecated QGL* classes have been removed.

Fixes: QTBUG-74408

-    \class QGLColormap
-    \brief The QGLColormap class is used for installing custom colormaps into
-    a QGLWidget.
-
-    \obsolete
-    \inmodule QtOpenGL
-    \ingroup painting-3D
-    \ingroup shared
-
-    QGLColormap provides a platform independent way of specifying and
-    installing indexed colormaps for a QGLWidget. QGLColormap is
-    especially useful when using the OpenGL color-index mode.
-
-    Under X11 you must use an X server that supports either a \c
-    PseudoColor or \c DirectColor visual class. If your X server
-    currently only provides a \c GrayScale, \c TrueColor, \c
-    StaticColor or \c StaticGray visual, you will not be able to
-    allocate colorcells for writing. If this is the case, try setting
-    your X server to 8 bit mode. It should then provide you with at
-    least a \c PseudoColor visual. Note that you may experience
-    colormap flashing if your X server is running in 8 bit mode.
-
-    The size() of the colormap is always set to 256
-    colors. Note that under Windows you can also install colormaps
-    in child widgets.
-
-    This class uses \l{implicit sharing} as a memory and speed
-    optimization.
