Vlad Zahorodnii 935fa6a9e1 Move ownership of Shadow to Toplevel
This decouples the management of Shadow from the scene window and allows
multiple items share the same Shadow.

Currently, kwin has a single scene graph, but it makes sense to create a
scene graph per output as they could have different layers, etc. This
would also allow QtQuick share more textures with kwin, which is worth
doing for optimization purposes in the future.
