Also request the OpenGL RHI backend explicitly, like all the other
similar examples (d3d11underqml, and so on) do.
Calling resetOpenGLState() in this example is pointless because it
happens before returning from the custom rendering function, and the
endExternalCommands() call achieves the same internally, i.e. the rhi
will know that cached state cannot be used anymore. There are other
valid uses cases for resetOpenGLState() but this example does not have
those.

The headers are moving from QtGui to QtOpenGL. By avoiding the
qualification we can keep them compiling either way. Also, add
opengl-private to make the types available.
Also removed the QGraphicsRotation hack to get access to the projected
rotation function of QMatrix4x4. The function is public now.

It has to be written following the new split approach (beforeRendering
for resource setup, beforeRenderPassRecording to issue the actual
underlay draw calls), but it will then work both with and
without QSG_RHI=1.

Opt in via environment variables:
QSG_RHI=1 -> enable using QRhi instead of GL
QSG_RHI_BACKEND -> set to vulkan, metal, d3d11, gl to override the default
(the default is d3d11 on Windows, metal on Mac, gl elsewhere)
Or force a given rhi backend via the existing
QQuickWindow::setSceneGraphBackend().
Otherwise the default behavior is the same as before, the rhi code path
is never active by default.
-no-opengl builds are supported in the sense that they work and default
to the software backend. However, the rhi code path cannot currently be
used in such builds, even though QRhi from qtbase is fully functional
with Vulkan, D3D, or Metal even when qtbase was configured with
-no-opengl. This cannot be utilized by Quick atm due to OpenGL usage
being all over the place in the sources corresponding to the default
backend, and those host the rhi code path as well. This will be cleaned up
hopefully in Qt 6, with the removal all direct OpenGL usage.
Other env.vars.:
QSG_RHI_DEBUG_LAYER=1 -> enable D3D debug or Vulkan validation layer
(assuming the system is set up for this)
QSG_RHI_SHADEREFFECT_DEBUG=1 -> print stuff from ShaderEffect
QSG_SAMPLES=1,2,4,... -> MSAA sample count (but QSurfaceFormat works too)
QT_D3D_ADAPTER_INDEX=0,1,... -> D3D adapter index
QT_VK_PHYSICAL_DEVICE_INDEX=0,1,... -> Vulkan physical device index
QSG_RHI_UINT32_INDEX=1 -> always use uint index data (both
merged/unmerged, convert when needed - with some rhi backends this is
implicit)
QSG_RENDER_LOOP -> to override the render loop as usual. The default
with RHI is threaded for Metal, threaded for Vulkan on Windows, basic
for Vulkan on Linux and Android (to be checked later), while the existing
rules apply for OpenGL.
Not supported when running with QRhi:
- particles
- compressed atlases (though this is transparent to the apps)
- QSGRenderNode
- QQuickRenderControl
- QQuickFramebufferObject
- certain QQuickWindow functionality that depends directly on OpenGL
- anisotropic filtering for textures
- native text may lack some gamma correction
- QSGEngine applicability unclear
- some QML profiler logs may be incorrect or irrelevant

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.
Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to

Documentation for that fact, and the windowChanged signal.
Fix existing QQuickItem subclasses which didn't call
QQuickItem::itemChange. Examples should rather connect to the
windowChanged() signal.
