Subject: Cleanup: Separate the sub-tree layering out of QtQuick into the scene
 graph

This basically renames QQuickShaderEffectTexture to QSGDefaultLayer and
introduces QSGLayer as interface to be used. QQuickShaderEffectTexture is
generic for the scene graph and has no QtQuick dependencies. The interface
separation allows scene graph backends to customize layers.
