About the OpenGL module in Qt

[wangdaye078]

Starting from Qt6.0, classes QOpenGLXXXX (such as QOpenGLBuffer) have been migrated to the QtOpenGL module. Therefore, the <object type name="QOpenGLBuffer"/> in typesystem_gui.xml should be changed to <object type name="QOpenGLBuffer" before-version="6"/>, and then <object type name="QOpenGLBuffer" since-version="6"/> should be added to typesystem_opengl.xml. Other QOpenGLXXXXs should also be treated similarly, while the original QGLBuffer in typesystem_opengl.xml should be changed to <object type name="QGLBuffer Before-version=" 6 "/>
