Wayland QOpenGLContext->setNativeHandle() will still create a new GL context

      I'm attempting to render QML (using QQuickRenderControl based heavily on https://felgo.com/doc/qt/qtquick-rendercontrol-example/) within an external OpenGL context and have had success running with X11/GLX and Windows/WGL.

      I'm attempting to test with Wayland by passing a QEGLNativeContext to QOpenGLContext->setNativeHandle() and it seems from my cursory look through the Wayland backend, that QWaylandGLContext does not support wrapping a native context unlike QGLXContext.  This means a subsequent call to QOpenGLContext->create() will create a new OpenGL context which is not what I want.
