Retain meta data set on imported nodes

During the import process, many importer nodes are replaced with their
engine node counterparts. For example, ImporterMeshInstance3D is
replaced with a MeshInstance3D node. Any meta data set on these
importer nodes, i.e. through a GLTFDocumentExtension, are lost during
the conversion. This change copies over any meta data set on these
importer nodes to their engine counterparts.
