QOpenGLTexture: Set wrap mode if NPOT textures are not fully supported

The OpenGL wrap mode defaults to GL_REPEAT although it is not supported for
non-power-of-two textures on hardware that only has limited support.

I.e. the following would create a texture with an invalid wrap mode:

    auto *t = new QOpenGLTexture(QOpenGLTexture::Target2D);
    t.setSize(123, 456);

This patch adds a check in QOpenGLWindow::setSize to see if it's called with a
non-power-of-two size on hardware without full support, and if so sets wrapMode
to ClampToEdge (which should work on devices with limited support).
