QmlDesigner: Add navigator preview tooltip for materials

Request 3D preview image for material instances from puppet
to show on tooltip.

Support for effect previews is also done, but handler for it is not
registered, as effects cannot be shared between windows due to
issue QTBUG-86616.

Also refactored the preview image support out of navigator
to make it more accessible by other components.
