assume QOpenGLWidget is available
QOpenGLWidget was introduced in Qt 5.4.
* acinclude.m4 (OCTAVE_CHECK_QT_OPENGL_OK): Delete.
(OCTAVE_CHECK_QT_VERSION): Delete use. Don't define separate macros
and compiler flag variables for QtOpenGL module. Include them with
the other Qt compiler flags.
* subst-config-vals.in.sh, subst-cross-config-vals.in.sh,
configure.ac, GLCanvas.cc, GLCanvas.h, module.mk, build-env.h,
build-env.in.cc, toplev.cc: Eliminate checks for Qt QOpenGLWidget.
Assume it is always available. Eliminate QtOpenGL configuration
variables.
