This reverts commit 7b1331c789df0ac12d7cf5aa5f8967b8651a4cfa.
Revert of commercial license headers is required for Qt 5.15.3
opensource release.

Updated header.COMM to the files in tqtc-qtdeclarative.
Examples, documentation files or tests are not updated.
The commercial license header may contain some
additional lines so that its line count equals with
the earlier license header. Reason for this is that
some autotests use hard coded line numbers and a
change in the line count causes failures in tests.

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).

Instead use QT_CONFIG(foo). This change actually detected a few
mis-spelled macros and invalid usages.

rendererInterface() should not require isSceneGraphInitialized() to be
true - the API and language queries like graphicsApi() have no need for the
scenegraph, they only need the plugin to be loaded, i.e. that the QQuickWindow
is constructed.
This is the key to be able to make GraphicsInfo report graphicsApi and
shaderType with the correct values as early as possible - meaning as soon
as the item is associated with a window. The initialization of the
scenegraph (the exact timing of which varies backend to backend) does not
matter here.
The fragment and vertex shader property setting is now unified in the two
ShaderEffect implementations:
- If the component is complete, the shader is attempted to be processed
right from the setter.
- Otherwise the item will trigger processing once the component is
complete.
- If there is no window when processing is trigerred, it is deferred via
polish.
To implement item polish handling we need a new virtual in
QQuickItemPrivate since we cannot intrdouce virtuals into the public
classes.
This way one can write a condition (and later potentially use file
selectors) like this:
fragmentShader: GraphicsInfo.shaderType == GraphicsInfo.GLSL ? "..." : ...
without having to worry about getting an unintended value processed due to
GraphicsInfo not yet reporting an up-to-date value.
parseLog() forces, for GL at least, shader processing to prevent autotests
from breaking.

Make it clear with the naming that this is specific to OpenGL.

Rename RendererInfo to GraphicsInfo. Deprecate OpenGLInfo and move
the surface format properties into GraphicsInfo. Move also the
shader info properties from ShaderEffect.
