Add QSGSpriteNode to the Scenegraph Adaptation Layer

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.
