QmlDesigner: Fix dynamic properties on material library init

Browse Source 
Nodes with dynamic properties cannot be reparented under a newly
created node in the same transaction without breaking said properties.

To work around this issue, ensureMaterialLibraryNode() was split into
two transactions. This also meant removing ensureMaterialLibraryNode()
call from materialLibraryNode(), so now material library will only be
created in response to model attach or qtquick3d import addition.
This should still cover all cases where user doesn't manually remove
the material library node.

Fixes: QDS-8095
