Rename setSceneGraphBackend to setGraphicsApi

...and fix up the docs.

The string-based setSceneGraphBackend() stays of course (the docs have
been enhanced, however). The GraphicsApi enum-based overload is now
renamed to setGraphicsApi().

Using the same name for both functions is a historical artifact, reflecting
the evolution (5.0 - 5.8 - 5.14). In 6.0 we can give it a more appropriate
name, since it does not have much to do with "backends" from the user's
perspective.
