Fix items in layouts not being rendered when layers are used

A layer effect is apparently considered a child item of the layout
that manages the item, and this causes issues when layouting.

As was done for positioners in 865b4ec8, exclude
any items for which QQuickItemPrivate::isTransparentForPositioner()
returns true from layouting. As that commit made QQuickItemLayer set it
to true when the layer is enabled, QQuickShaderEffectSource will be
excluded from layouting.
