This patch partially reverts 098ba086530ccd555369a9ea88f3c6668726ab81.
Only QtWebGL will use separate buffers for indices and vertices. This
patch gives a performance boost.

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).

This adds experimental automatic atlasing of ETC-compressed textures
(to be expanded to additional formats), similar to existing atlas
support of QImages. It is off by default, and can be enabled with
QSG_ENABLE_COMPRESSED_ATLAS=1.

This was fixed in Qt 5.9.0 by 9921b48c83490b450241d6c172f1375ab4efb6b1,
but refactoring caused this change to be lost.
This is just porting the fix to the refactored class hierarchy.

Most core Qt Quick items use one of the nodes provided by the Scenegraph
Adaptation Layer, however the two items that provide support for Sprites
created their own custom nodes. There was significant redundancy in
this, and it made it only possible to use the OpenGL adaptation. The
AnimatedSprite and SpriteSequence items have been cleaned up, and now
use the new QSGSpriteNode.

Because traditional context plugins (see scenegraph-playground) may want
to subclass these instead of the generic base interfaces with no
ready-made OpenGL functionality.

Allow calling initialize(nullptr) regardless of which scenegraph backend
is in use.

Currently the Qt Quick module depends on either the OpenGL or OpenGLES
headers being available at build time. Since we are adding support for
adaptations that do not depend on OpenGL, it should be possible to build
Qt Quick in environments that do not have OpenGL development headers.
This does present many challenges though because in some cases GL types,
and classes that require OpenGL are part of the public APIs. However
since these classes were never available when QT_NO_OPENGL was defined,
it should be possible to redefine the function signatures under this
scenario, since it's not possible to break binary compatibility if there
never were any binaries to break compatibility with.
One of the bigger changes that was necessary to facilitate this change
is creating interfaces out of QSGContext and QSGRenderContext. Here the
default behavior was usage of OpenGL directly, even though subclasses
could override all OpenGL usage. Making them interfaces should bring
QSGContext and QSGRenderContext more in line with the other classes
present in the adaptation layer.
